Operating information

The following table describes the operating modes available on the S9 AutoSet and S9 Elite.
Mode
CPAP mode
A fixed pressure is delivered with optional Expiratory Pressure
Relief (EPR). EPR can help ease any discomfort that your
patient experiences when breathing out during treatment.
AutoSet mode
The AutoSet algorithm automatically adjusts pressure in
response to inspiratory flow limitation, snore and apnoea.
AutoSet mode offers optional EPR. You can set the minimum
and maximum allowable treatment pressures.

EPR technology

Designed to make therapy more comfortable, EPR maintains optimal treatment for the patient during
inhalation and reduces the delivered mask pressure during exhalation. You can select EPR in either CPAP
or AutoSet mode.
