Full Menu Access Mode  
The ventilator has two levels of menu access, Full and Limited. Full  
Menu Access allows you to alter all available settings. Limited Menu  
access permits the user to alter only those prescription parameters  
Note: The Full Menu Access key  
sequence can be performed  
either from the Power Off screen  
that affect patient comfort, such as Rise Time, Flex, and Ramp Start  
Pressure, if those parameters are available as part of the prescription.  
The ventilator defaults to Full Menu Access mode.  
or from the Monitor screen.  
Note: When the airflow is off  
and AC power is removed from  
the device for more than 5  
minutes, the device will enter  
a low power mode to save  
battery life. When the device is  
in low power mode, the Setup  
key sequence will be ignored.  
Press the Start/Stop button, or

Warnings and Cautions  
Caution: U.S. federal law restricts this device to sale by or on the order of a physician.  
Warnings  
A warning indicates the possibility of injury to the user or operator.  
Patient Monitoring Prior to placing a patient on the ventilator, a clinical assessment should  
be performed to determine:  
•
•
•
The device alarm settings  
Needed alternative ventilation equipment  
If an alternative monitor (i.e., an alarming Pulse Oximeter or  
Respiratory Monitor) should be used  
Alternative  
Ventilation  
For ventilator dependent patients, always have alternate ventilation  
equipment, such as a back-up ventilator, manual resuscitator, or similar  
device, available.  
Ventilator dependent patients should be continuously monitored by  
qualified personnel. These personnel should be prepared to provide  
alternate therapy in the event of ventilator failure or inoperative  
equipment.  
Patient Disconnect For ventilator dependent patients, do not rely on any single alarm  
Protection  
to detect a circuit disconnect condition. The Low Tidal Volume, Low  
Minute Ventilation, Low Respiratory Rate, and Apnea alarms should  
be used in conjunction with the Circuit Disconnect and Low Peak  
Inspiratory Pressure alarms.  
Test the operation of the circuit disconnect function daily and  
whenever a change is made to the patient circuit. An increase in circuit  
resistance can prevent proper operation of some alarms.  
Speaking valves, Heat Moisture Exchangers (HMEs), and filters create  
additional circuit resistance and may affect the performance of alarms  
chosen for circuit disconnect protection.  
Do not set the Low Peak Inspiratory Pressure alarm too low, or the  
system may not detect large circuit leaks or a patient disconnect.

Personnel  
Qualifications  
Trilogy200 is a restricted medical device designed for use by  
Respiratory Therapists or other trained and qualified caregivers under  
the supervision of a physician.  
The prescription and other device settings should only be changed on  
the order of the supervising physician.  
The operator of the ventilator is responsible to read and understand  
this manual before use.  
Modes of  
Ventilation  
The device can provide therapies typically associated with both  
ventilator dependent and non-dependent patients. The mode of  
ventilation, circuit type, and alarm strategies should be chosen after a  
clinical evaluation of each patient’s needs.  
C-Flex, Bi-Flex, and AVAPS are intended for use by adult patients.  
SD Card  
Prescription  
Changes  
When you change the device prescription, alarms, and other settings  
using the SD card, Trilogy200 requires that the caregiver review and  
verify the changes prior to the changes being used by the device. The  
caregiver or health care professional is responsible to ensure that the  
prescription settings are correct and compatible with the patient after  
using this feature. Installing the wrong prescription for a particular  
patient may result in improper therapy, lack of appropriate safety  
monitoring, and risk of death or injury to the patient.  
Electrical  
Interference  
This device is intended for use in the electromagnetic environment  
specified in Chapter 13 of this manual. The user of this device should  
make sure it is used in a compatible environment.  
Portable and mobile RF communications equipment should be  
used no closer to any part of the device, including cables, than the  
recommended separation distance calculated using the information  
provided in Chapter 13 of this manual.  
Battery Back-up  
Power  
The internal battery is NOT intended to serve as a primary power  
source. It should only be used when other sources are not available or  
briefly when necessary; for example, when changing power sources.  
The ventilator has a two-stage low battery alarm. The medium priority  
alarm indicates that approximately 20 minutes of operation remain,  
and the high priority alarm indicates that less than 10 minutes of  
operation remain. Actual run time may be more or less than this and  
varies with battery age, environmental conditions, and therapy.  
Immediately seek an alternate power source when the “Low Battery”  
alarm appears. Complete power failure and loss of therapy is imminent.

Operating  
and Storage  
Temperatures  
Do not use this device if the ambient temperature is warmer than  
40˚ C (104˚ F). If the device is used at room temperatures warmer than  
40˚ C, the temperature of the airflow may exceed 43˚ C. This could  
cause system alarms, thermal irritation, or injury to the patient’s airway.  
Bacteria Filter  
Philips Respironics recommends that a main line outlet bacteria filter  
(Part Number 342077) be used whenever the device is used for invasive  
therapy or if the ventilator may be used on multiple patients.  
Patient Circuits  
(General)  
The ventilator should only be used with patient interfaces (e.g., masks,  
circuits and exhalation ports) recommended by Philips Respironics.  
Proper operation of the device, including alarms, with other circuits has  
not been verified by Philips Respironics and is the responsibility of the  
health care professional or respiratory therapist.  
When adding any components to the breathing system, the flow  
resistance and dead space of the added components such as  
humidifiers, speaking valves, Heat Moisture Exchangers (HMEs) and  
filters should be carefully considered in relation to the potential for  
adverse effects on the patient’s ventilatory management and device  
alarms.  
Passive Circuits  
Active Circuits  
An exhalation port is required when using a passive circuit.  
For the passive circuit, at low expiratory pressures, the flow through  
the exhalation port may be inadequate to clear all exhaled gas from  
the tubing – some rebreathing may occur. Rebreathing of exhaled air  
for longer than several minutes can in some circumstances lead to  
suffocation.  
Only use the active exhalation devices designed for Trilogy200. Philips  
Respironics has not verified proper operation of other active exhalation  
devices, and their use may result in improper or unsafe device  
operation.  
With active exhalation circuits, the exhalation device must be operating  
properly for the ventilator to deliver therapy. The exhalation device  
should be inspected on a daily basis and replaced whenever necessary.  
System Checkout  
Do not use the ventilator on a patient until a system checkout has been  
performed. See Chapter 10 of this manual.  
To make sure the device is operating properly at start-up, always verify  
that the audible tone sounds and the alarm LEDs light red and then  
yellow momentarily. Contact Philips Respironics or an authorized  
service center for service if these indications do not occur at start-up.

Remote Alarms  
When using a remote alarm, make sure you fully test the remote alarm  
connector and cable by verifying that:  
– Annunciated alarms on the ventilator are also  
annunciated on the remote alarm.  
– Disconnecting the remote alarm cable from the  
ventilator or from the remote alarm results in an alarm  
notification at the remote alarm.  
The remote alarm should be tested daily.  
Oxygen  
When administering fixed-flow supplemental oxygen, the oxygen  
concentration may not be constant. The inspired oxygen concentration  
will vary, depending on the pressures, patient flows and circuit leak.  
Substantial leaks may reduce the inspired oxygen concentration to less  
than the expected value. Appropriate patient monitoring should be  
used, as medically indicated, such as an alarming pulse oximeter.  
This device DOES NOT alarm for loss of the low flow oxygen supply.  
This device is intended to be connected to a low flow (0-15 l/min)  
oxygen source such as an oxygen concentrator or other oxygen source  
equipped with a pressure regulator (set to 50 PSI or less) and a flow  
regulator/meter.  
Do not connect the device to an unregulated or high pressure oxygen  
source.  
The device may result in incorrect flow and tidal volume measurements  
and improper operation of related alarms if you add low flow oxygen  
directly into the patient circuit or mask instead of using the oxygen  
inlet on the back of the ventilator.  
Oxygen supports combustion. Oxygen should not be used while  
smoking or in the presence of an open flame.  
If oxygen is used with the device, the oxygen flow must be turned  
off when the device is not in use. Explanation of the Warning:  
When the device is not in operation and the oxygen flow is left on,  
oxygen delivered into the tubing may accumulate within the device’s  
enclosure.  
Fire or Explosion  
The ventilator should not be operated in the presence of flammable  
gasses. This could cause a fire or explosion.

7
Alarms  
Respond immediately to any alarm. It may indicate a potentially  
life-threatening condition. Refer to the Alarms and Troubleshooting  
chapters for more information.  
Visually monitor the patient and ventilator at all times during an Alarm  
Silence period. Allowing alarms to continue without intervention may  
result in harm to the patient.  
If the high priority “Low Internal Battery”message appears,  
immediately connect the ventilator to an alternate power source. If no  
alternate power source is available, immediately place the patient on  
an alternate source of ventilation.  
If the “Ventilator Inoperable”alarm occurs, immediately place the  
patient on an alternate source of ventilation.  
You should not rely on any single alarm to detect a circuit disconnect  
condition. The Low Tidal Volume, Low Minute Ventilation, Low  
Respiratory Rate, and Apnea alarms should be used in conjunction with  
the Circuit Disconnect alarm.  
Make sure the alarm volume is set loud enough to be heard by the  
caregiver. Consider the use of a remote alarm.  
Trilogy200 offers the following circuit type selections:  
•
•
•
Passive  
Active Flow  
Active PAP (Proximal Airway Pressure )  
The Passive circuit type provides an ESTIMATE of Vte.  
Only the Active Flow circuit type directly measures exhaled tidal  
volume (Vte).  
The Active PAP circuit type DOES NOT measure Vte and only provides  
for an indication of the delivered tidal volume (Vti).  
Improperly  
Functioning  
Ventilator  
If you notice any unexplained changes in the performance of the  
device, if it is making unusual sounds, if the device or detachable  
battery are dropped, if water is spilled into the enclosure, or if the  
enclosure is cracked or broken, discontinue use and contact Philips  
Respironics or an authorized service center for service.

Maintenance  
Follow the service recommendations provided in Chapter 7 of this  
manual.  
Periodically inspect electrical cords, cables, and the detachable battery  
pack for damage or signs of wear. Discontinue use and replace if  
damaged.  
Repairs and adjustments must be performed by Philips Respironics-  
authorized service personnel only. Unauthorized service could cause  
death or injury, invalidate the warranty, or result in costly device  
damage.  
Cleaning  
To avoid electrical shock, always unplug the power cord from the wall  
outlet before cleaning the ventilator.  
(Refer to Chapter 7  
for detailed cleaning  
instructions.)  
Do not immerse the device in any fluids or spray the device with water  
or cleaners. Clean the device with a cloth dampened with an approved  
cleaner.  
If the device has been exposed to rain or dampness, dry the device  
including the area around the power cord connection with the power  
cord disconnected from the device before applying AC power.  
Cautions  
A caution indicates the possibility of damage to the device.  
Storage  
The internal and detachable batteries will self-discharge in storage. If it  
is desired to keep the batteries fully charged (for example, as a back-  
up ventilator), plug the device into AC power for about eight hours  
every 16 days. Alternatively, the ventilator may be left continuously  
connected to AC power without battery degradation.  
Allowing the batteries to fully discharge will not harm the batteries or  
lose device settings, but may require a longer battery charge time prior  
to use.

Operating  
and Storage  
Temperatures  
The device may only be operated at temperatures between 5˚ C and  
40˚ C (41˚ F and 104˚ F).  
Do not operate the device in direct sunlight or near a heating  
appliance because these conditions can increase the temperature of  
the airflow delivered to the patient.  
Prolonged operation or storage at elevated temperatures may reduce  
the service life of the battery and other internal components of the  
ventilator.  
The ventilator has an internal and detachable Lithium-Ion Battery. Do  
not expose the device or detachable battery to temperatures above  
40˚ C (104˚ F) during use, or above 60˚ C (140˚ F) during storage. This  
will reduce battery life and may increase the risk of fire or damage the  
battery.  
Condensation  
Condensation may affect operation or accuracy of the device. If the  
device has been exposed to either very hot or very cold temperatures  
during storage, allow it to adjust to ambient temperature before  
starting therapy.  
Air Filter  
The reusable foam inlet filter is required to protect the ventilator from  
dirt and dust. Wash periodically and replace when damaged for proper  
operation.  
Cooling Air Vents  
Battery Life  
Do not block the cooling air vents located on the base and the rear  
of the device. This may cause the device to overheat in high ambient  
temperatures or at high therapy settings.  
The internal and detachable batteries wear out based on the amount  
of use (hours or full charge-discharge cycles). The battery capacity and  
life are also reduced by operation at higher temperatures.  
Detachable Battery Only use the Philips Respironics Trilogy Detachable Battery with the  
ventilator.  
Cleaning  
Do not steam autoclave the ventilator. Doing so will destroy the  
ventilator.  
Do not immerse the device in liquid or allow any liquid to enter the  
enclosure or inlet filter.  
Do not spray water or any other solutions directly onto the ventilator.  
Do not use harsh detergents, abrasive cleaners, or brushes to clean the  
ventilator system. Use only cleaning agents and methods listed in this  
manual.

Patient Circuit  
Exhalation valves, patient circuits, and water traps are shipped clean,  
not sterile. Cleaning and disinfection of these parts should follow  
individual institution processes and conform to guidelines provided by  
Philips Respironics with each accessory.  
External DC Power  
Do not use the same external battery to operate both the ventilator  
and any other equipment such as power chairs.  
An external battery should only be connected to the ventilator using  
the Philips Respironics Trilogy External Battery Cable. This cable is  
fused, pre-wired, and properly terminated to ensure safe connection  
to a standard deep-cycle, lead acid battery. Use of any other adapter or  
cable may cause improper operation of the ventilator.  
The ventilator should only be connected to an automotive electrical  
system using the Philips Respironics Trilogy Automotive Adapter  
(when available). This adapter is fused, filtered, and designed for safe  
connection to a standard automotive electrical system. Use of any  
other adapter or cable may cause improper operation of the ventilator.  
Do not operate the ventilator from a car electrical system when  
starting the vehicle or jump-starting the vehicle. Electrical transients  
during starting may cause improper operation of the ventilator.  
Electrostatic  
Discharge (ESD)  
Do not use antistatic or conductive hoses or conductive patient tubing  
with the device.  
Notes

System Overview  
This ventilator provides both pressure control and volume modes of  
therapy. The device can provide non-invasive or invasive ventilation.  
It can be used to provide total therapy to patients as they progress  
from non-invasive to invasive ventilation.  
When prescribed, the device provides numerous special features to  
help make patient therapy more comfortable. For example, the ramp  
function allows you to lower the pressure when trying to fall asleep.  
The air pressure will gradually increase until the prescription pressure  
is reached. Additionally, the Flex comfort feature provides increased  
pressure relief during the expiratory phase of breathing.  
The ventilator can be operated using several different power  
sources, including an internal Lithium-Ion battery. This battery is  
automatically used when the detachable Lithium-Ion battery pack,  
external Lead Acid battery, or AC power are not available.

3. Modes, Features, and Alarms  
Therapy Modes  
The device provides Pressure Control Ventilation (PCV) and Volume  
Control Ventilation (VCV) for non-invasive and invasive patients.  
Pressure Control ventilation delivers a prescribed pressure to  
the patient according to set breath rate and set inspiration time  
parameters. This means that each breath is controlled so that a  
prescribed amount of pressure is delivered to the patient. The device  
offers six different Pressure Control modes of operation:  
•
•
•
•
•
•
CPAP – Continuous Positive Airway Pressure  
S – Spontaneous Ventilation  
S/T – Spontaneous/Timed Ventilation  
T – Timed Ventilation  
PC – Pressure Control Ventilation  
PC-SIMV – Pressure Controlled Synchronized Intermittent  
Mandatory Ventilation  
Volume Control ventilation delivers a prescribed inspired tidal  
volume to the patient according to set breath rate and set inspiratory  
time parameters. This means that each breath is controlled so that a  
prescribed tidal volume is delivered to the patient. The device offers  
three different Volume Control modes of operation:  
•
•
•
AC – Assist Control Ventilation  
CV – Control Ventilation  
SIMV – Synchronized Intermittent Mandatory Ventilation

Breath Types  
There are four breath types that apply to the Volume Control and  
Pressure Control ventilation therapy modes:  
•
•
•
•
Spontaneous  
Mandatory  
Assisted  
Sigh  
Spontaneous Breath  
A Spontaneous breath is triggered by the patient. Breaths are  
initiated by the patient’s inhalation effort, and air delivery is  
controlled based on the current pressure or volume setting. Breaths  
are terminated by either the ventilator settings or by the patient’s  
exhalation effort, depending on the mode selected.  
Mandatory Breath  
A Mandatory breath (or machine breath) is completely controlled by  
the ventilator. The ventilator controls both the beginning (triggering)  
and end (cycling) of the inspiratory phase.  
Assisted Breath  
An Assisted breath is controlled by both the patient and the ventilator.  
Breaths are initiated by the patient’s effort and air delivery is controlled  
by the current pressure or volume settings. Volume Assisted breaths  
will deliver the prescribed Tidal Volume within the prescribed  
Inspiratory Time. Pressure Assisted breaths will deliver the prescribed  
Inspiratory Pressure for the prescribed Inspiratory Time. Breaths are  
terminated when the Inspiratory Time setting has been reached.  
Sigh  
A Sigh breath is a breath where 150% of the prescribed volume  
is delivered. The device will deliver this breath once every 100  
Mandatory or Assist breaths when the Sigh setting is enabled. Sigh  
breaths are only available in volume modes of ventilation.

Pressure Control Ventilation Therapy Modes  
Pressure Control ventilation modes deliver a prescribed pressure to  
the patient.  
Continuous Positive Airway Pressure (CPAP) Mode  
In the Continuous Positive Airway Pressure (CPAP) mode, the device  
delivers a continuous pressure to the patient at all times. All breaths  
in this mode are Spontaneous breaths.  
Spontaneous (S) Mode  
In Spontaneous (S) mode, the device delivers bi-level pressure  
support. This mode provides only spontaneous breaths. In this  
mode, an Inspiratory Positive Airway Pressure (IPAP) is delivered  
during inhalation and a lower Expiratory Positive Airway Pressure  
(EPAP) is delivered during exhalation. The following illustration  
describes these concepts.

Spontaneous/Timed (S/T) Mode  
In Spontaneous/Timed (S/T) mode, the device delivers bi-level  
pressure support. This mode provides Spontaneous and Mandatory  
breaths. A Mandatory breath is delivered if the patient does not  
spontaneously breathe within the prescribed Breath Rate (BPM)  
setting. This ensures that the patient receives a minimum number  
of breaths per minute. In this mode, an IPAP is delivered during  
inhalation and a lower EPAP is delivered during exhalation. The  
duration of a Spontaneous breath is determined by the patient effort.  
The duration of a Mandatory breath is determined by the inspiratory  
time setting. The following illustration describes these concepts.

Timed (T) Mode  
In Timed (T) mode, the device delivers bi-level pressure support.  
This mode delivers Mandatory breaths only. A Mandatory breath  
is delivered according to the prescribed BPM and inspiratory time  
settings. This also means that the ventilator will not respond to  
patient effort. In this mode, an IPAP is delivered during inhalation and  
a lower EPAP is delivered during exhalation. The following illustration

Pressure Control - Synchronized Intermittent Mandatory  
Ventilation (PC-SIMV) Mode  
The Pressure Control – Synchronized Intermittent Mandatory  
Ventilation (PC-SIMV) mode provides Spontaneous, Assist, and  
Mandatory breaths. This mode uses a time window to decide  
what type of breaths should be delivered. This time window is the  
maximum time between breaths according to the set Breath Rate.  
When you enter PC-SIMV mode, the time window is started. If  
the patient does not trigger a breath, the ventilator will provide  
a Mandatory breath when the time expires and then begin the  
process again. Mandatory breaths deliver the Pressure setting during  
inhalation and a lower Peak End Expiratory Pressure (PEEP)  
during exhalation.  
Chapter 3 Modes, Features, and Alarms  
Download from Www.Somanuals.com. All Manuals Search And Download.  
26  
During the time window, if patient effort is detected, either a  
Spontaneous or an Assist breath is delivered for the first effort. If the  
last breath delivered was Mandatory, then a Spontaneous breath is  
delivered for the first patient effort of the window. If the last breath  
delivered was an Assist or Spontaneous breath, then an Assist breath  
is delivered for the first patient effort of the window. Assist breaths  
deliver the Pressure setting during inhalation and the PEEP setting  
during exhalation.  
During the time window, if patient effort continues to be detected  
(after the first patient triggered breath), Spontaneous breaths are  
delivered for the remainder of the window. The figure below provides  
example breath patterns in PC-SIMV mode.

Volume Control Ventilation Therapy Modes  
Volume Control ventilation modes deliver a prescribed inspired tidal  
volume according to a set Breath Rate and a set Inspiratory Time.  
Control Ventilation (CV) Mode  
In Control Ventilation (CV) mode, the device delivers volume control  
therapy. This mode provides only Mandatory breaths. A Mandatory  
breath is delivered according to the prescribed BPM setting for the  
prescribed Inspiratory Time. This also means that the ventilator  
will not respond to patient effort. In this mode, the Tidal Volume is  
delivered during inhalation and PEEP is delivered during exhalation.

Assist Control (AC) Mode  
In Assist Control (AC) mode, the device delivers volume control  
therapy. This mode provides Assist and Mandatory breaths. An Assist  
breath is started when there is patient effort, but it is ended when  
the Inspiratory Time setting has been met. A Mandatory breath  
is delivered if the patient does not spontaneously breathe within  
the prescribed BPM setting. This ensures that the patient receives  
a minimum number of breaths per minute. In this mode, the Tidal  
Volume is delivered during inhalation and PEEP is delivered during  
exhalation. The following illustration describes these concepts.

Synchronized Intermittent Mandatory Ventilation (SIMV) Mode  
In Synchronized Intermittent Mandatory Ventilation (SIMV) mode, the  
device delivers both volume control and pressure control therapy.  
This mode provides Spontaneous, Assist, and Mandatory breaths.  
This mode uses a time window to decide what type of breaths should  
be delivered. This time window is the maximum time between  
breaths according to the set Breath Rate.  
When you enter SIMV mode, the time window is started. If the  
patient does not provide any effort, the ventilator will provide a  
Mandatory Volume breath when the time expires and then begin the  
process again. Mandatory breaths deliver the Tidal Volume setting  
during inhalation and provide a lower Peak End Expiratory Pressure  
(PEEP) during exhalation.

deliver the prescribed Tidal Volume during inhalation and the PEEP  
setting during exhalation.  
During the time window, if patient effort continues to be detected  
(after the first patient triggered breath), Spontaneous breaths are  
delivered for the remainder of the window. Spontaneous breaths  
deliver the prescribed Pressure Support setting above PEEP during  
inhalation and PEEP during exhalation. The figure below provides

Therapy Mode Features  
The device has several additional features that enhance patient  
comfort.  
Flex Comfort Feature  
Note: Flex is not available if  
AVAPS is enabled or if an active  
circuit is used.  
The device consists of a special comfort feature called Flex. The  
device provides the Flex feature in CPAP mode and S mode. This  
feature is only available when Auto-Trak is enabled.  
Note: The patient has access to  
this setting, if Flex is enabled.  
C-Flex  
When in CPAP mode, if C-Flex is enabled, it enhances patient comfort  
by providing pressure relief during the expiratory phase of breathing.  
In the following diagram, the dashed lines represent normal CPAP  
therapy in comparison to the bold line representing C-Flex. C-Flex  
levels of 1, 2, or 3 progressively reflect increased pressure relief.  
Note: C-Flex is not available if  
CPAP is set to 4 cm H2O.  
Note: C-Flex, Bi-Flex and AVAPS  
are intended for use by adult  
patients.

Rise Time  
In S, S/T, PC, T, PC-SIMV, and SIMV modes, rise time is the amount  
of time it takes the device to change from the expiratory pressure  
setting to the inspiratory pressure setting. Rise time levels of 1, 2,  
3, 4, 5, or 6 progressively reflect slowed response of the pressure

AVAPS Feature  
Note: AVAPS is only available if  
Average Volume Assured Pressure Support (AVAPS) is a feature  
available in the S, S/T, PC, and T modes. It helps patients maintain  
a tidal volume (VT) equal to or greater than the target tidal volume  
(Volume setting in the ventilator) by automatically controlling the  
pressure support (PS) provided to the patient. The AVAPS feature  
adjusts PS by varying the IPAP level between the minimum (IPAP Min)  
and maximum (IPAP Max) settings. AVAPS averages VT and changes  
the PS value gradually. This occurs over several minutes. The rate of  
change is slow, so that the patient is not aware of breath-to-breath  
pressure changes.  
you are using a passive circuit.  
Note: C-Flex, Bi-Flex and AVAPS  
are intended for use by adult  
patients.  
As patient effort decreases, AVAPS automatically increases PS to  
maintain the target tidal volume. The IPAP level will not rise above  
IPAP Max, even if the target tidal volume is not reached. Conversely,  
as patient effort increases, AVAPS will reduce PS. IPAP will not fall  
below IPAP Min, even if the target tidal volume is exceeded.  
If the Ramp function has been activated, it will take precedence over  
the AVAPS feature. Once ramp is complete, AVAPS will resume.

result in a flow of less than 20 l/min. Therefore, for some settings,  
a Ramp flow pattern may provide a pattern that more closely  
resembles a Square flow pattern.

Sigh Feature  
The sigh feature is available for Volume ventilation modes only.  
When the sigh feature is enabled, the ventilator delivers a sigh breath  
in place of every 100th mandatory or assisted breath delivered  
regardless of the mode of operation (i.e., AC, CV, and SIMV). The Sigh  
breath is delivered using a volume equal to 150% of the set volume  
that was in effect when the breath was initiated.

Triggering  
The device can be set to trigger breaths using the Auto-Trak or Flow  
Trigger sensitivity features.  
Digital Auto-Trak Sensitivity  
An important characteristic of the device is its ability to recognize  
and compensate for unintentional leaks in the system and to  
automatically adjust its trigger and cycle algorithms to maintain  
optimum performance in the presence of leaks. This feature is known  
as Digital Auto-Trak Sensitivity. The following sections examine this  
function in detail by describing the leak tolerance function and  
sensitivity.  
Leak Tolerance  
A microprocessor monitors the total flow of the patient circuit and  
calculates patient flow values.  
A. Leak Estimation: Average and Parabolic  
The device uses two leak estimation algorithms. A conservation  
of mass algorithm is used to compute the average leak for a given  
pressure support relationship. This average leak is used when large  
leak variations are present in the system. Average leak is a high  
estimate during EPAP pressure and a low estimate during IPAP  
pressure. A better leak estimate, enabled by the digital system, is the  
parabolic leak algorithm. Parabolic leak is proportional to the square  
of the patient pressure; therefore, the leak estimate is correlated to  
the changing patient pressure. Both algorithms include unintentional  
circuit leak and are averaged over several breaths.  
B. Patient Flow  
The total circuit flow is comprised of the circuit leak and the patient  
flow. The calculated patient flow is the total flow minus the circuit  
leak. Patient flow is a primary input into the triggering and cycling  
mechanisms.

Auto-Trak Sensitivity  
Note: Auto-Trak is only  
available if you are using a  
passive circuit.  
An essential feature of the device while operating in all modes is  
its ability to effectively sense spontaneous breathing efforts, which  
causes the ventilator to trigger to inspiration and cycle to expiration.  
Because no preset sensitivity threshold can assure patient and  
machine synchrony with changing breathing efforts and circuit  
leaks, the device continuously tracks patient breathing patterns  
and automatically adjusts sensitivity thresholds to ensure optimum  
sensitivity as breathing patterns change or as circuit leaks change.  
The algorithms used to ensure optimum sensitivity are the Volume  
Trigger, Shape Signal, Spontaneous Expiratory Threshold (SET), Flow  
Reversal, Maximum IPAP Time, and Volume Control Cycle.  
Volume Trigger (Expiration to Inspiration):  
The volume trigger is one method used to trigger inspiration during  
spontaneous breathing in all modes except T and CV. The volume  
trigger threshold is 6 ml of accumulated patient inspiratory volume.  
When patient effort generates inspiratory flow causing 6 ml of  
volume, inspiration is triggered.  
Shape Trigger/Shape Cycle (Expiration to Inspiration) (Inspiration to  
Expiration):  
The shape trigger/cycle is another method used to trigger inspiration  
and/or cycle from inspiration to expiration during spontaneous  
breathing in all modes except T and CV. This method continuously  
tracks patient inspiratory and expiratory flow and adjusts the  
spontaneous trigger and cycle thresholds for optimum sensitivity.  
The Shape Signal appears as a shadow image of the patient’s actual  
flow. The shape signal functions as a sensitivity threshold at either  
inspiration or expiration. When the patient’s flow rate crosses the  
shape signal the unit changes pressure levels. The following figure  
illustrates how the shape signal is super-imposed onto the actual  
waveform to trigger and cycle off IPAP. The shape signal is created  
by offsetting the signal from the actual patient flow by 15 l/min and  
delaying it for a 300 msec period. This intentional delay causes the  
shape signal to be slightly behind the patient’s flow rate.

39  
Spontaneous Expiratory Threshold (Inspiration to Expiration):  
A second method used to cycle to expiration during spontaneous  
breathing in all modes except T, CV, AC, and SIMV, is called  
Spontaneous Expiratory Threshold (SET). The SET rises in proportion  
to the inspiratory flow rate on each breath. When the SET and actual  
patient flow value are equal, the unit cycles to expiration.

Flow Reversal (Inspiration to Expiration):  
As flow begins to decrease during inspiration, a flow reversal can  
occur due to a large leak around the mask or because the patient’s  
mouth is open. When the device senses this flow reversal, it  
automatically cycles to expiration.  
Maximum IPAP Time (Inspiration to Expiration):  
The maximum inspiratory time is determined by the adjustment of  
the Inspiratory time setting. A maximum IPAP time of 3.0 seconds  
acts as a safety mechanism to limit the time spent in inspiration  
during spontaneous breathing. For mandatory or assisted breaths,  
the maximum inspiratory time will equal the Inspiratory time setting  
up to 5.0 seconds.

40  
Volume Control Cycle (Inspiration to Expiration) (Only available  
during Volume Control Therapy)  
An Inspiratory Time setpoint limits the time spent in inspiration  
during breathing in all modes. Once the time limit is reached, the unit  
automatically cycles to expiration.  
Flow Trigger  
Flow trigger provides a manual setting that allows for breath  
initiation and termination based on a set flow trigger sensitivity and  
flow cycle sensitivity.  
Flow Trigger Sensitivity (Expiration to Inspiration):  
The flow trigger initiates when the patient’s inspiratory effort creates a flow  
equal to or greater than the flow trigger sensitivity setting. The method of  
the flow trigger is dependent upon the circuit type that is chosen.  
Leak Compensation:  
When using the Passive Circuit configuration, compensation for both the  
intentional and unintentional leak is included in the triggering method.  
When using the Active PAP Circuit configuration, leak compensation  
is not available.  
When using the Active Flow Circuit configuration, flow trigger with  
leak compensation may be enabled. The default setting when using  
the Active Flow Circuit is Leak Compensation On. The clinician has  
the option to turn off leak compensation; however, unintentional  
leak will not be compensated. Both options measure the flow at the  
proximal flow sensor.  
Note: Enabling Leak  
Compensation when using the  
Active Flow Circuit configuration  
only affects triggering and does  
not affect tidal volume delivery  
or Vte measurement.  
Flow Cycle Sensitivity (Inspiration to Expiration):  
This cycling method is only active if the Flow Trigger has been  
selected for the Trigger Type. As flow begins to decrease during  
inspiration, if the patient flow is less than the flow cycle sensitivity  
setting, the device will cycle to expiration.  
For example: if the flow cycle sensitivity setting is set to 75%, when  
the flow has decreased by 25% of the peak flow, the device will cycle  
to the EPAP/PEEP level.

You can operate the ventilator using an external battery, detachable  
battery, or the internal battery.  
CAUTION  
External Battery  
Do not use the same external  
battery to operate both the  
ventilator and any other equipment  
such as power chairs.  
The ventilator can operate from a 12 VDC deep cycle marine-type  
(lead acid) battery using the Philips Respironics Trilogy External  
Battery Cable. This cable is pre-wired and properly terminated to  
ensure safe connection of an external battery to the ventilator.  
Battery operating time depends on the characteristics of the battery  
and usage of the device.  
CAUTION  
An external battery should only  
be connected to the ventilator  
using the Philips Respironics  
Trilogy External Battery Cable.  
This cable is fused, pre-wired and  
properly terminated to ensure  
safe connection to a standard  
deep cycle lead acid battery. Use  
of any other adapter or cable  
may cause improper operation  
of the ventilator.  
Due to a variety of factors, including battery chemistry, battery age,  
and use profile, the capacity of the external battery as shown on the  
device display is only an estimate of the actual remaining capacity.  
Refer to the instructions supplied with the Philips Respironics Trilogy  
External Battery Cable for detailed information on how to operate  
the device using an external battery.

Detachable Battery Pack  
Philips Respironics offers a detachable Lithium-Ion battery pack. To  
use the detachable battery pack, snap the battery into place on the  
back of the ventilator, as shown in the following illustration. When  
the device is not connected to an AC power source or an external  
battery, the detachable battery will power the device, if attached.  
The length of time the ventilator will operate on battery power  
depends on many factors such as device settings, battery charge  
level, and condition or age of the battery. When fully charged, a new  
battery can power the ventilator for approximately three hours under  
typical patient conditions.  
CAUTION  
The detachable and internal  
batteries wear out based on  
the amount of use (hours or full  
charge-discharge cycles). The  
battery capacity and life are also  
reduced by operation at higher  
temperatures.  
Whenever the ventilator is connected to AC power, it will  
automatically recharge the detachable battery pack. A completely  
discharged detachable battery will reach 80% charge status within 8  
hours, when charging at approximately 23˚ C ambient temperature.  
CAUTION  
Only use the Philips Respironics  
Trilogy Detachable Battery with  
the device.  
Insert and securely latch the detachable battery into the device as  
shown below.

WARNING  
Internal Battery  
The device contains an internal battery that can be used as a back-  
up power source. It is intended for use during short periods while  
switching between external power sources, emergency situations, or  
short durations when the user needs to be mobile. The length of time  
the ventilator will operate on internal power depends on many factors  
such as device settings, battery charge level, and condition or age of the  
battery. When fully charged, a new battery can power the ventilator for  
approximately three hours under typical patient conditions.  
The internal battery is NOT  
intended to serve as a primary  
power source. It should only be  
used when other sources are  
not available, or briefly when  
necessary; for example when  
changing power sources.  
Whenever the ventilator is connected to AC power, it will  
automatically recharge the internal battery. A completely discharged  
internal battery will reach 80% charge status within 8 hours when  
charging at approximately 23˚ C ambient temperature.

Circuit Type  
Note: To change the circuit  
type, you must be in the  
Setup screen with the airflow  
turned off. See the Full Menu  
Access Mode section for more  
information.  
There are three circuit types you can select:  
•
•
•
Passive  
Active PAP  
Active Flow  
Note: When the Circuit Type  
setting is set to Passive Circuit,  
all Ramp Start Pressure settings  
in all modes will maintain the  
minimum range.  
The Passive circuit type uses the Whisper Swivel II passive exhalation  
device. The Active PAP circuit type uses an active exhalation device  
with a proximal air pressure sensing connection. The Active Flow circuit  
type uses an active exhalation device with a proximal flow sensor.  
Note: When the Circuit Type  
setting is set to Active PAP or  
Active Flow, the Flex and AVAPS  
features are unavailable.  
When using the Passive circuit, the ventilator displays estimated  
patient pressures based on the resistance of the standard patient  
circuit (Whisper Swivel II with 1.8 meter tubing). Adding accessories  
to the patient circuit (humidifier, water trap, etc.) may cause an  
increase in circuit resistance and cause the device to display slightly  
higher pressures than what is actually delivered to the patient.  
With the Active PAP or Active Flow circuit type selected, patient  
pressure is measured directly and is not affected by any change in  
circuit resistance.

75  
The Passive circuit provides leak compensation. When using the Passive  
circuit in Volume Ventilation, the set Vti is delivered to the patient  
above the calculated circuit and cuff (or mask) leak. This is different  
from traditional active circuit ventilation where the cuff (or mask) leak  
reduces the tidal volume delivered to the patient. Volume ventilation  
with the Passive circuit delivers an inspiratory tidal volume close to  
the device setting regardless of leak; this should be considered when  
transitioning a patient from an active to a passive circuit. With a Passive  
circuit, Vte is estimated based on the calculated sum of circuit and cuff  
(or mask) leak.  
The Active Flow circuit monitors proximal flow and proximal  
pressure. When using the Active Flow circuit configuration, flow  
trigger with leak compensation may be enabled. The default setting  
when using the Active Flow Circuit is Leak Compensation On. The  
clinician has the option to turn off leak compensation; however,  
unintentional leak will not be compensated. Both options measure  
the flow at the proximal flow sensor. Leak compensation is not  
available in the Active with PAP circuit configuration.  
WARNING  
Circuit Disconnect  
You should not rely on any  
single alarm to detect a circuit  
disconnect condition. The Low  
Tidal Volume, Low Minute  
Ventilation, Low Respiratory  
This setting enables or disables the circuit disconnect alarm. If  
enabled, an audible alarm will sound when a large, continuous air  
leak (such as mask removal) has been detected in the circuit.  
Rate, and Apnea alarms should  
be used in conjunction with the  
Circuit Disconnect alarm.  
You can choose Off to disable the alarm. Or, you can increase or  
decrease the setting from 5 to 60 seconds in 5 second increments.  
For example, a setting of 10 means that the alarm will sound after the  
circuit has been disconnected for 10 seconds.  
Apnea  
This setting enables or disables the apnea alarm. If enabled, an  
audible alarm will sound when an apnea is detected.  
You can choose Off to disable the alarm. Or, you can increase or  
decrease the setting from 10 to 60 seconds in 5 second increments.  
For example, a setting of 10 means that the alarm will sound if the  
time between spontaneous breaths exceeds 10 seconds.

sensitivity is set at 10%, this will  
result in the least sensitivity.  
If you set the Trigger Type to Flow Trigger, the Flow Cycle  
Sensitivity setting displays. You can increase or decrease the  
setting from 10 to 90 percent (%) in 1% increments.  
As flow begins to decrease during inspiration,  
if the patient flow is less than the flow cycle set  
point, the device will cycle to expiration. For  
example: if the flow cycle is set to 75%, when the  
flow has decreased by 25% of the peak flow, the  
device will cycle to the EPAP/PEEP level.

Updating Prescriptions Using the SD Card  
WARNING  
When you change the device  
prescription, alarms and other  
settings using the SD card,  
Trilogy200 requires that the  
caregiver review and verify the  
changes prior to the changes  
being used by the device.

settings are correct and  
With the Trilogy200, you can update the patient’s prescription using  
the SD Card. This feature lets you update a single prescription or  
both prescriptions if the dual prescription feature is enabled. The  
prescription update can occur either when the ventilator is off or on.

“Change Prescription?” message appears on the display:  
2. Select No to cancel the prescription update process and return  
to the previous display (the black screen if the airflow was off or  
the Monitor/Standby screen if the airflow was on). Select Yes to  
start the prescription update process. Once the prescription is  
read in and validated, one of the following screens appears on  
the display to allow you to ensure the prescription is correct:  
compatible with the patient  
after using this feature. Installing  
the wrong prescription for a  
particular patient may result  
in improper therapy, lack of  
appropriate safety monitoring,  
and risk of death or injury to the  
patient.

6. Ventilator Alarms  
This chapter describes the ventilator alarms and what you should do  
if an alarm occurs.  
There are three types of alarms:  
Note: If multiple alarms occur  
•
•
•
High Priority – Require immediate response by the  
operator  
at the same time, all alarms are  
processed and displayed, but  
the alarms are ordered first by  
priority and then by occurrence,  
with the newest, highest priority  
alarms at the top of the list.  
The alarm precedence is in the  
following order: high priority,  
medium priority, low priority,  
and informational messages.  
Medium Priority – Require prompt response by the  
operator  
Low Priority – Require operator awareness. These alarms  
alert you to a change in the ventilator status.  
Additionally, the ventilator also displays informational messages and  
confirmation alerts that notify you of conditions that need attention  
but do not qualify as alarm conditions.  
Note: Not all alarms are  
available in every therapy  
mode; some alarms are mode-  
dependent.

Audio Pause and Alarm Reset Features  
This section describes the Audio Pause and Alarm Reset features.  
Audio Pause  
When an alarm occurs, you can temporarily silence the audible  
indicator by pressing the Alarm Indicator/Audio Pause button. The  
alarm is silenced for 60 seconds and then will sound again if the  
cause of the alarm has not been corrected. Each time the Alarm  
Indicator/Audio Pause button is pressed, the alarm silence period  
resets to one minute.  
When Audio Pause is active, the Alarm Indicator/Audio Pause symbol  
(
) appears if you are on the Monitor screen. Additionally, an  
“Audio Pause”message displays in the menu banner on the Alarm  
Display screen.  
You can ‘pre-silence’alarms that have not yet occurred by pressing  
the Alarm Indicator/Audio Pause button while no alarms are active.  
Then, if an alarm occurs, the audible indicator does not sound until  
the Audio Pause time limit has expired. This can be useful during  
patient setup, so caregivers can prevent alarms from sounding that  
they know will occur during the setup process. The LED and display  
will still show the alarm, but the audible alarm will not sound.  
Alarm Reset  
The Reset button is used to clear the currently active alarm(s) from  
the display and stop the LED and audible alarm indicator. This button  
should be selected after the situation causing the alarm(s) has been  
corrected. All active alarms are cancelled and alarm detection is  
restarted when this button is selected.  
The ventilator self-cancels certain alarms if the cause of the alarm is  
corrected, shutting off the alarm LED, the audible alarm, and the alarm  
background color. However, the alarm text remains on the screen. You  
can manually reset an alarm by pressing the Left button (Reset). The  
Audio Pause function is cancelled if the alarm is manually reset.

Alarm Volume Control  
WARNING  
As explained in Chapter 5, you can adjust the Alarm Volume from  
the Options menu. You can select Loud or Soft, depending on your  
preference.  
Make sure the alarm volume is  
set loud enough to be heard by  
the caregiver. Consider the use of  
a remote alarm.  
What to Do When An Alarm Occurs  
WARNING  
You should not rely on any  
single alarm to detect a circuit  
disconnect condition. The Low  
Tidal Volume, Low Minute  
Ventilation, Low Respiratory  
Rate, and Apnea alarms should  
be used in conjunction with the  
Circuit Disconnect alarm.  
Complete the following steps when an alarm occurs:  
1. Whenever an alarm occurs, first always observe the patient  
and ensure that adequate ventilation and oxygenation (if  
appropriate) are available.  
2. Look at the alarm indicators and listen to the audible alarm  
sound. Note the color of the Alarm Indicator/Audio Pause button  
(red or yellow) and whether the LED is solid or flashing.  
3. Look at the display to check the alarm message that appears on-  
screen and whether it is highlighted in red or yellow.  
4. Press the Alarm Indicator/Audio Pause button to temporarily  
silence the audible alarm. A visual indicator displays if you are on  
the Monitor screen (  
), or an “Audio Pause”message appears in  
the menu banner on the Alarm Display screen.  
5. Look up the alarm in the alarm descriptions later in this chapter  
to determine the source of the alarm and the appropriate action.

recommended that you clean  
the filter in the morning and  
alternate using the two foam  
filters provided with the system  
to ensure sufficient drying time  
for the cleaned filter.  
4. Wash the gray foam filter in warm water with a mild detergent.  
Rinse thoroughly to remove all detergent residue. Allow the filter  
to air dry completely before reinstalling it. If the foam filter is torn  
or damaged, replace it. Only Philips Respironics-supplied filters  
should be used as replacement filters.

Cleaning the Patient Circuit  
Cleaning the reusable circuit is important in the hospital and in the  
home. Circuits infected with bacteria may infect the user’s lungs.  
Clean the respiratory circuit on a regular basis. If you are using a  
disposable circuit, dispose of and replace it on a regular basis.  
Follow your institution’s protocol for cleaning the circuit. Philips  
Respironics recommends that you perform the cleaning twice a  
week under normal conditions and more frequently as required.  
If the patient uses the device on a 24 hour a day basis, it may be  
convenient to have a second breathing circuit so you can switch  
circuits while one is being cleaned.  
CAUTION  
Exhalation devices, patient  
circuits, and water traps are  
shipped clean, not sterile.  
Cleaning and disinfection  
of these parts should follow  
individual institution processes  
and conform to guidelines  
provided by Philips Respironics  
with each accessory.  
Cleaning Instructions (Reusable Circuits)  
Clean the patient circuit twice a week, or follow your institution’s  
protocol.  
1. Disconnect the circuit from the device, and disassemble the  
circuit for cleaning. Thoroughly wash your hands.  
2. Using a mild detergent, such as liquid dishwashing soap, clean  
all accessible surfaces of the circuit. Do not clean using alcohol.  
3. Rinse the circuit with tap water, removing all remaining detergent.  
4. Prepare a solution of one part white vinegar to three parts  
distilled water. An average beginning quantity is 16 ounces  
vinegar to 48 ounces distilled water. The actual amount will vary  
according to individual needs. Regardless of the quantity the  
ratio must remain 1 part:3 parts. Soak the circuit in this solution  
for one hour. Rinse the circuit completely with tap water.

134  
Supplemental Oxygen Warnings  
•
When administering fixed-flow supplemental oxygen,  
the oxygen concentration may not be constant. The  
inspired oxygen concentration will vary, depending on  
the pressures, patient flows and circuit leak. Substantial  
leaks may reduce the inspired oxygen concentration  
to less than the expected value. Appropriate patient  
monitoring should be used, as medically indicated, such  
as an alarming pulse oximeter.  
•
•
•
•
This device DOES NOT alarm for loss of the low flow  
oxygen supply.  
Oxygen supports combustion. Oxygen should not be  
used while smoking or in the presence of an open flame.  
Do not connect the device to an unregulated or high  
pressure oxygen source.  
The device may result in incorrect flow and tidal volume  
measurements and improper operation of related alarms  
if you add low flow oxygen directly into the patient  
circuit or mask instead of directly adding it into the  
oxygen inlet on the back of the ventilator.  
•
•
If oxygen is used with the device, the oxygen flow must  
be turned off when the device is not in use. Explanation  
of the Warning: When the device is not in operation  
and the oxygen flow is left on, oxygen delivered into the  
tubing may accumulate within the device’s enclosure.  
WARNING  
The remote alarm should be  
tested daily. When using a  
remote alarm, make sure you  
fully test the remote alarm  
connector and cable by verifying  
that:  
The ventilator should not be operated in the presence of  
flammable gasses. This could cause a fire or explosion.

where P is the maximum output power rating of the  
transmitter in watts (W) according to the transmitter  
manufacturer and d is the recommended separation  
distance in meters (m).  
Field strengths from fixed RF transmitters, as determined  
by an electromagnetic site surveya, should be less than  
the compliance level in each frequency range.b  
Interference may occur in the vicinity of equipment  
marked with the following symbol:  
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.  
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and  
reflection from structures, objects, and people.  
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile  
radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy.  
To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should  
be considered. If the measured field strength in the location in which the device is used exceeds the applicable  
RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is  
observed, additional measures may be necessary, such as re-orienting or relocating the device.  
b
Over the frequency range 150 kHz to 80 MHz, the field strengths should be less than 3 V/m.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters  
(m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output  
power of the transmitter manufacturer.  
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.  
Note 2: The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz;  
13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.  
Note 3: An additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in the  
ISM frequency bands between 150 kHz and 80 MHz and in the frequency range of 80 MHz and 2.5 GHz to decrease the  
likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into  
patient areas.  
Note 4: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and  
reflection from structures, objects and people.
