I've been on CPAP now for about two months, and I am consistently waking up after 3-4 hours of using my CPAP. I wake up feeling really uncomfortable, and almost like it is hard to breathe and I almost always end up taking my mask off and falling back asleep.
I am using a ResMed AirSense 10 Elite with the built in humidifier and heated hose. I haven't changed my pressure settings since starting CPAP, and my machine is set to 4-20cmH2O. I've also changed the auto-ramp time to the max of 45min. I have already messed around with the temperature and humidity level to get it at a comfortable level. Seen a lot of suggestions on forums to enable "Pressure Relief" on this device, but I don't see this options in my settings (is it possible it was disabled by the DME company or my doctor?).
Also tried a few different masks including a F&P Simplus full face mask, a ResMed AirFit F30i, and a ResMed AirFit P30i. Also tried a cushion from an N30i with the P30i frame (I think they're the same frame, my DME provider sent the cushions to me with the P30i to try). I was able to get good seals with both the F&P mask and the P30i, but the P30i is definitely my favorite so far.
I just discovered OSCAR thanks to the forums, so I've been tracking my data with myAir which I really don't like. myAir is reporting a good mask seal with an AHI of < 5 (usually less than 1). So myAir says that my CPAP is working as expected, and I do see some benefits from using it, but ultimately I just haven't been able to use it for more than a few hours at a time.
Any advice or suggestions are greatly appreciated.
