DreamStation BiPAP autoSV User Manual
Patient circuits
The ventilator should only be used with compatible patient interfaces (e.g., masks,
circuits and exhalation ports). 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. 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 flow of air out of
the mask. When the device is turned on a functioning properly, new air from the
device flushes 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 suffocation.
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
airflow and result in rebreathing of exhaled air.
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 pull or stretch the tubing. This could result in circuit leaks.
Verify operation of the Patient Disconnect alarm with any changes in the patient
circuit.

ventilator
If you notice any unexplained changes in the performance of the device, if it is
making unusual sounds, if water is spilled into the enclosure, or if the enclosure is
cracked or broken, discontinue use and contact your home care service provider.
Circuit disconnect
You should not rely on any single alarm to detect a circuit disconnect condition. The
Low Minute Ventilation and Apnea alarms should be used in conjunction with the
Circuit Disconnect alarm.
Test the operation of the circuit disconnect function whenever a change is made to
the circuit. An increase in circuit resistance can prevent proper operation of some
alarms.
Power cord
Route the power cord to the outlet in a way that will prevent the cord from being
tripped over or interfered with by chairs or other furniture.
This device is activated when the power cord is connected.
Use only power cords supplied by Philips Respironics for this device. Use of power
cords not supplied by Philips Respironics may cause overheating or damage to the
device.
Accessories
To ensure that you receive safe, effective therapy, use only Philips Respironics
accessories. The use of accessories, transducers, and cables other than those
specified by Philips Respironics may result in increased emissions or decreased
immunity of the device.
