Operating Information; Epr Technology; Epr Checklist - ResMed S9 Series Clinical Manual

Operating information

The following table describes the operating modes available on the S9 Series.
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 apnea. AutoSet mode
offers optional EPR. You can set the minimum
and maximum allowable treatment pressures.
APAP mode
APAP mode treats apneas up to 10 cm H
does not differentiate between different types
of apneas. The APAP algorithm automatically
adjusts pressure in response to inspiratory flow
limitation, snore and apnea.

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 CPAP ,
AutoSet or APAP modes.

EPR checklist

ü You can set EPR to Off, Ramp Only, Full Time.
ü You can select an EPR Level of Off, 1, 2, 3 cm H
ü In CPAP mode you can set the EPR Inhale to Med or Fast.
ü When EPR is enabled, the delivered pressure will not drop below a minimum pressure of 4 cm H
regardless of the settings.
