•The Trilogy Evo Universal is not intended for MRI or anesthesia applications, and is not intended to be permanently
mounted in EMS vehicles.
•When disposing of this device or any accessories, ensure you comply with your local regulations. Dispose of any
potentially biohazardous waste according to your local regulations.

Instructions for Use | Introduction
Warnings 6
•This device is intended for use in the electromagnetic environment specified in the “EMC Information” chapter. Ensure
the environment is compatible. Portable and mobile RF communications equipment, including cables, should be no closer
to any part of the device than the recommended separation distance indicated in the “EMC Information” chapter.
•This device is not made with natural rubber latex.
•Do not use the ventilator in a hyperbaric chamber.
•Do not use the ventilator in the presence of nitric or nitrous oxide.
•Do not use the ventilator with helium or in the presence of mixtures in combination with helium.
•Route all cables in a manner to prevent injury, such as tripping or strangulation, to the patient and caregiver.
Clinical
•Before placing a patient on the ventilator, perform a clinical assessment. Considerations should include:
-Choosing alarm settings
-Whether alternative ventilation equipment is required
-Whether alternative monitors are required, such as Vte monitoring for Active PAP circuit, pulse oximeter or
respiratory monitor with alarm
•Trilogy Evo Universal is a restricted medical device. It is designed for use by respiratory therapists or other trained and
qualified caregivers under the supervision of a physician. Only the supervising physician’s orders authorize changes to the
prescription and other device settings. Before using Trilogy Evo Universal, you must read and understand this manual.
•When using the ActivePAP circuit, CO2monitoring is required to measure exhaled carbon dioxide, in accordance with ISO
80601-2-55.
•Unintentional leaks cause exhaled volume and expired CO2values to differ from actual patient values.
•The caregiver or health care professional is responsible for verifying any changes to the device, prescription, or other
settings before applying changes. The caregiver or health care professional is responsible for ensuring settings are correct
and compatible with the patient. Using the wrong prescription for a patient may result in improper therapy, lack of
appropriate safety monitoring, or risk of death or injury to the patient.
Alternate Ventilation
•To avoid patient death or serious injury, ventilator-dependent patients require immediate access to alternate ventilation
equipment, such as a back-up ventilator or manual resuscitator.
•Qualified personnel should monitor ventilator-dependent patients continuously. Personnel should be prepared to provide
alternate therapy in the event of ventilator failure or inoperative equipment.
Alarms
•Do not rely on any single alarm to detect a disconnected circuit.
•Respond immediately to any high priority alarm. It may indicate a potentially life-threatening condition.
•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 Battery alarm occurs, 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.
•When using a remote alarm, make sure you fully test the remote alarm connector and cable by verifying that:
-You can hear the ventilator’s audible alarms on the remote alarm.
-The remote alarm signals when you disconnect the remote alarm cable from the ventilator or from the
remote alarm
•Test the operation of the circuit disconnect function daily and whenever the patient circuit is changed. An increase in
circuit resistance can prevent proper operation of some alarms.

Instructions for Use | Introduction
Warnings 7
•Speaking valves, heat moisture exchangers (HMEs), humidifiers, 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.
Accessories
•Use Trilogy Evo Universal only with accessories intended for use with this device. Otherwise, adverse performance
including increased electromagnetic emissions or decreased electromagnetic immunity of this equipment can occur. For a
list of accessories, such as patient interfaces, circuits, exhalation ports, and cables, see the Trilogy Evo Universal
accessories guide. Ensure accessories and parts are compatible before you connect a patient to the device. Consult the
accessory’s instructions before use.
•The air-inlet foam filter is required to protect the ventilator from dirt and dust. See the “Service and Maintenance”
chapter for maintenance instructions.
•Be certain that any breathing system filter used with this device complies with ISO 23328-1 and ISO 23328-2. · To prevent
patient or ventilator contamination, we recommend you use a Respironics-approved main flow bacteria filter (Part
Number 342077) on the patient gas outlet port. Filters not approved by Respironics may degrade system performance.
•When adding any components (such as humidifiers, speaking valves, heat moisture exchangers, and filters) to the
breathing system, consider the flow resistance and dead space in relation to the potential for adverse effects on the
patient’s ventilator management and device alarms.
•Nebulization or humidification can increase the resistance of breathing system filters. Monitor the breathing system
frequently for increased resistance and blockage.
•Gas added by the use of a pneumatic nebulizer can adversely affect ventilator accuracy.
•When using a passive circuit an exhalation port is required. 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.
•Do not use antistatic or conductive hoses or conductive patient tubing with the device.
•The ventilator system (used with patient circuit accessories, such as patient interface devices, humidifiers, water traps, and
circuit tubing) may contain small parts that could result in a choking hazard.
•Be certain that any humidifier in use, including any heated breathing tube, complies with ISO 8185.

Instructions for Use | Therapy Modes and Controls
Overview 17
3. Therapy Modes and Controls
Overview
Trilogy Evo Universal therapy modes can be used for invasive and noninvasive ventilation with all circuit types, including mouthpiece ventilation.
Breath Types
Trilogy Evo Universal can deliver the following breath types:
oMandatory: Ventilator-initiated, time-cycled
oAssist-Control: Patient-initiated, time-cycled
oSpontaneous: Patient-initiated, patient-cycled
Triggering and Cycling
Patient triggers
Auto-Trak is a flow trigger with rules that make patient-triggering and cycling more comfortable for the patient. The system uses multiple
algorithms to detect the start and end of the breath. Also, it automatically adjusts the trigger and cycle sensitivity to optimize synchronization
between the patient and the ventilator.
Sensitive Auto-Trak is a more sensitive version of Auto-Trak
Flow trigger initiates a breath when the patient’s inspiratory effort creates a flow equal to or greater than the flow trigger sensitivity setting. A
lower number is more sensitive. As inspiratory flow begins to decrease, the device cycles to expiration when the patient flow is less than the
percentage of peak flow, based on the flow-cycle sensitivity setting.
Ventilator trigger
Time Trigger is time-based, defined by the Breath Rate setting.
Flow patterns
Ramp wave pattern: airflow starts high and decreases throughout inspiration of the breath.
Square wave pattern: airflow is generally constant throughout inspiration of the breath.
Therapy Modes Overview
Control Modes: breaths are assist-control or mandatory.
•A/C-PC: Assist control – assist-control and mandatory breaths with pressure control
•A/C-VC: Assist control – assist control and mandatory breaths with volume control
Spontaneous modes: the patient initiates all breaths.
•CPAP: Continuous positive airway pressure
•PSV: Pressure support ventilation

Instructions for Use | Therapy Modes and Controls
Overview 18
Mixed modes: breaths are spontaneous, assist-control, or mandatory.
•S/T: Spontaneous/timed ventilation – spontaneous breaths with pressure support and mandatory breaths with pressure control
•SIMV-PC: Synchronized intermittent mandatory ventilation (pressure control) – spontaneous breaths with pressure support, assist—
control breaths and mandatory breaths with pressure control
•SIMV-VC: Synchronized intermittent mandatory ventilation (volume control) – spontaneous breaths with pressure support, assist—
control breaths and mandatory breaths with volume control
Low Tidal Volume Therapy
For low tidal volume therapy, use the infant/pediatric external flow sensor. See the instructions included with the sensor.
When setting volumes greater than or equal to 50ml, use any circuit type.
When setting volumes greater than or equal to 35ml, use either the active flow or dual limb circuits.
The following pressure modes are available for patients who require a tidal volume less than 35ml:
•A/C-PC
•PSV
•S/T
•SIMV-PC
Therapy Mode Comparison Table
For all modes, the breath type varies based on time of patient inspiration. The breath type is always ventilator-initiated and mandatory when the
Trigger Type is set to Off.
