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)

Guide Error //2
Can it plugged into a receptacle in Cuba with just an adapter?
My resmed air 11 does not work anymore and I have a flashing snowflake
The ResMed AirSense 11 shows a flashing snowflake icon when it is in cooling mode after use. If the icon remains flashing even while the device is in use, it may indicate an issue with airflow or internal components. Possible causes include blockages, inadequate ventilation, excess water in the hose, or a mechanical/electronic fault. To fix it, check for blockages, ensure proper airflow, drain excess water, and restart the machine. If the issue persists, the device may require professional repair.

KEEPS SHUTTING OF
The ResMed AirSense 11 may keep shutting off due to several reasons:
1. Weak Wireless Connection – If the device has a poor signal, try moving it to a location with a stronger connection, unplugging it for 60 seconds, and then powering it back on.
2. Running for Too Long – If the machine has been plugged in for weeks or months without being turned off, it may need a power cycle. Unplug it for 60 seconds, then plug it back in and restart it.
3. Turning Off Too Soon – If the device is powered down immediately after use, it may not have enough time to transmit data. Leave it on after stopping therapy to allow data transfer.
If these steps do not resolve the issue, professional repair may be necessary.

where do I find steps for Error Message 4
To resolve Error Message 4 for the ResMed AirSense 11, follow these steps:
1. Check the environment temperature – Ensure the device is not covered and allow it to cool before reuse.
2. Restart the device – Disconnect the power supply, then reconnect it.
3. Check the filter – If the filter is blocked, replace it and allow the device to cool down before restarting.
4. Inspect the air tubing – Remove any blockages in the tubing and press "OK" to restart therapy.
5. Check for water in the air tubing – If present, remove any blockages and press "OK" to restart therapy.
6. Inspect the main PCA board – If the issue persists, the main PCA board may be faulty and needs replacement.
These steps should help diagnose and resolve Error 4.

Sleep hours not correct. Unit used to track properly. How do I fix this
To fix incorrect sleep hour tracking on the ResMed AirSense 11 using SleepHQ, you have two options:
1. Edit sessions manually: You can adjust sleep session times night by night.
2. Set a permanent time offset: If your machine is consistently off by a specific amount (e.g., 30 minutes), you can apply a permanent time offset. Click the three vertical dots in the top right, select "Edit session times," and enter the time offset in seconds (e.g., -3600 for 1 hour earlier). This shifts all sessions automatically.
These steps help correct inaccurate sleep times from the CPAP data.
