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 (109˚ F). This
could cause system alarms, thermal irritation, or injury to the patient's
airway.
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.
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.
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.
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.
Only use the active exhalation devices designed for Trilogy 202.
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.
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.
