USE
This chapter shows you how to use the device after installing it as described in the previous chapter.
It also shows you how to use the pressure increase (ramp) function and how to access information on
settings (you will not be able to alter these settings, but only view them).
WARNING
In the sections “Starting treatment” and “Stopping treatment” below, please follow the
directions carefully. If these directions are not followed, an accident can occur, especially where
the use of oxygen is concerned.
Starting treatment
Once the device has been installed in accordance with the instructions given in the previous chapter,
please follow the instructions below to start treatment:
1. Start the device by pressing the ON/OFF button.
The display shows the pressure available as well as the operation and compliance indicators (see
Figure 9).

NOTES
• The pressure unit displayed (hPa or cmH
2
O) can be modified by the Practitioner.
• The compliance operation indicator is displayed only after 15 minutes operation of the
device.
2. Put the nasal mask in place according to the instructions for its use. If a mask with exhalation
vent is used, it includes a hole by which the exhaled gases will be flushed and could not be
rebreathed. If a mask without exhalation vent is used, your doctor must provide you with an
adaptor allowing gases flushing as close as possible to the nose. Breathe normally.
WARNING
A CPAP mask with hose should not be worn unless the CPAP device is turned on and
operating properly. The vent hole(s) associated with the mask should never be blocked.
This CPAP machine is intended to be used with masks (or connectors) that have vent holes
to allow continuous flow of air out of the mask. When the CPAP device is turned on and
functioning properly, new air from the CPAP machine flushes the exhaled air out through
the mask vent hole. However, when the CPAP device is not operating, enough fresh air will
not be provided through the mask, and exhaled air may be rebreathed. Rebreathing of
exhaled air for longer than several minutes can in some circumstances lead to rebreathing
CO

or possible suffocation. This warning applies to most models of CPAP devices.
3. If you are using a heated humidifier, turn it on according to instructions for use.
4. If you are using oxygen, open the flow now.
