CPAP + O2 Concentrator Issue?
Resmed Autosense 10 CPAP (9-11.0) + Respironics Everflo Oxygen Concentrator (2L/min) user since around 2015. I live in CO at around 6200 ft. I only use Oxygen at night. Resmed ClimatelineAir Oxy Tube, although I've been using it unheated. Humidy level 5.
Previously, when I would turn on the O2 Concentrator (prior to starting the CPAP), I could feel air coming out of the CPAP mask in my nose from the O2 Concentrator. Noticed that I couldn't really feel it anymore. Could be my imagination though, or air temp. Also, maybe since I switched to newer N30i (more silicone/less plastic nose piece a while), it is just different?
Anyway, pulled out my old CMS50f Oxymeter to measure my O2 levels throughout the night. Haven't tested my O2 since 2018. Figured I would test with the O2 Concentrator, and without. To see if there is much difference. Anyway. This is what I ended up with. Looks like my O2 dipped below 88% quite a bit. Makes me a little worried? I have gained some weight over the last few years.
AHI seems pretty good. Maybe I need to up my O2 level? 3 L/min. I don't really want to pay for another sleep study, although I haven't had one in 7 years.
Any suggestions? Attached is my screenshot from last night.
