Respiratory effort related arousals reporting

Respiratory Effort Related Arousals (RERA) reporting is available on the AirSense 11 AutoSet and AirSense
11 Elite in all modes.
RERAs are periods of increasing respiratory effort which are terminated by an arousal. Increasing
respiratory effort will be seen as airflow limitation.These flow-based RERA events are logged and stored as
summary and/or detailed data and can then be viewed in one of ResMed's patient management systems.

Comfort features

Ramp

Designed to make the beginning of treatment more comfortable, ramp is available in all modes.
In AutoSet and AutoSet for Her mode, ramp time defines the period during which the pressure gradually
increases from a lower more comfortable start pressure to the minimum treatment pressure before the
auto-adjusting algorithm commences.
In CPAP mode, the pressure increases from a low pressure (Start Pressure) to the prescribed treatment
pressure.
Ramp Time can be set to Off, 5 to 45 minutes or Auto. When Ramp Time is set to Auto, the device will
detect sleep onset and then gradually increase from the start pressure to the minimum treatment pressure
at a rate of 1 cm H O (1 hPa) per minute. However, if sleep onset is not detected, the device will reach the
2
target pressure within 30 minutes.

Expiratory Pressure Relief

Designed to make therapy more comfortable, Expiratory Pressure Relief (EPR) maintains optimal treatment
for the patient during inhalation and reduces the delivered mask pressure during exhalation.
EPR On—EPR is enabled.
Off—EPR is disabled.
The following settings are only available if EPR is On:
EPR Type Full Time—If set to Full Time, EPR is enabled for the whole therapy session.
Ramp Only—If set to Ramp Only, EPR is only enabled during ramp time.
EPR Level 1, 2, 3 cm H
When EPR is enabled, the delivered pressure will not drop below a minimum pressure of 4 cm H
(4 hPa), regardless of the settings.
O (1, 2, 3 hPa)
