43 year old male, recently diagnosed with OSA, AHI of 15 (14, but 16 when supine) with severe hypoxia (73% O2 saturation). I was prescribed a ResMed Airsense 10 AutoSet with the AirFit F20 mask, settings are 5-15 on the APAP, with what I think is a sufficient amount of humidity.
All three nights went fine, meaning I slept as well and as long as I usually do. I usually wake up a few times to get comfortable, and the only difference was it took me more time to get to sleep with the mask on. After the first night, I woke up feeling exactly the same. However, after the 2nd and 3rd nights, I woke up feeling like a zombie. No energy, felt like I hadn’t slept at all.
Is this…normal? Is it some sort of period of adjustment and in X number of days, I’m gonna spring out of bed ready to take on the world? Or are my settings possibly wrong? I’ve got OSCAR installed (which is an AMAZING tool) and I don’t necessarily see anything too concerning, but I’m a total newbie at this, so…
Any guidance/hope would be appreciated by the more experienced folks.
