RE: Struggling to Lower AHI Below 5
You still have some flow limitations. You can raise your EPR from 2 to 3 and see how that affects your overall therapy.
A lot of members have battery back ups for power loss and for camping, etc.

RE: Struggling to Lower AHI Below 5
I will check it!
Can you please explain the mechanics behind the epr and flow limitations?

RE: Struggling to Lower AHI Below 5
EPR stands for expiratory pressure relief. It was created to make breathing feel more normal and natural by slightly lowering pressure every exhalation. But, it has an added benefit with most people who use it (I have personally seen it in many OSCAR charts uploaded here at ApneaBoard). After the exhale is completed, the pressure rises again and gives a little "boost" to the inhale to help overcome airway resistance (largely in the form of flow limitations). EPR can be set to 1, 2, and 3 (with 3 obviously giving the greatest boost to inhale).
A downside of EPR that can be common is increased CA's due to washing out more CO2 in the exhale (since it is easier to exhale with EPR enabled). When the % of CO2 in the bloodstream lowers, the signal to the brain to breathe diminishes. When CO2 levels build back up, then the brain sends the signal to breathe again.
