Patient
circuits and
tubing
The device should only be used with compatible patient interfaces (e.g., masks, circuits
and exhalation ports). Proper operation of the device with other circuits has not been
veried by Philips Respironics and is the responsibility of the health care professional.
A mask should not be used unless the device is turned on and operating properly. The
exhalation port(s) associated with the mask should never be blocked.
Explanation of warning: The device is intended to be used with special masks or
connectors that have exhalation ports to allow continuous ow of air out of the mask.
When the device is turned on and functioning properly, new air from the device ushes
the exhaled air out through the mask exhalation port. However, when the device is
not operating, enough fresh air will not be provided through the mask, and exhaled
air may be rebreathed. Rebreathing of exhaled air can, in some circumstances, lead to
suocation.
If you are using a full face mask (a mask covering both your mouth and your nose), the
mask must be equipped with a safety (entrainment) valve.
An exhalation port is required. Do not block the exhalation port. This can reduce airow
and result in rebreathing of exhaled air.
At low expiratory pressures, the ow through the exhalation port may be inadequate to
clear all exhaled gas from the tubing – some rebreathing may occur.
Do not pull or stretch the tubing. This could result in circuit leaks.
Do not cover the tubing with a blanket or heat it in an incubator or with an overhead
heater. This can aect the quality of the therapy or injure the patient.
The device should only be used with a compatible Philips Respironics mask, as
prescribed by your Healthcare Provider.
Accessories
To ensure that you receive the safe, eective therapy prescribed for you, use only
Philips Respironics accessories. The use of accessories, transducers, and cables other
than those specied by Philips Respironics may result in increased emissions or
decreased immunity of the device.
Pulse
oximeter
Use only Philips Respironics recommended pulse oximeter and sensors. Use of
incompatible sensors can result in inaccurate pulse oximeter performance.
Do not use a damaged pulse oximeter or sensor.
Before use, carefully read these instructions and the instructions for use provided with
the pulse oximeter and sensor.
