How I can get the data on average pressure applied on myAir or on the device?

Pressure data

Average pressure data is available on the AirSense 10. (not available on myAir).
Your AirSense 10 device has information on the average pressure. It is available in the Sleep Report section. To find your Sleep Report, go to your home menu. Then use the dial to scroll down to ‘Sleep Report’ and click enter using the dial. There is a guide how to access the sleep report on this website:
In addition, you can adjust "Period" using the dial from 1 month to 1 day, 1 week & etc.
