oxygen levels drop overnight

oxygen levels drop overnight
New user. Resmed air sense10 loaner and an airfit nasal pillow. Why do oxygen readings drop over night?? 95-93. If I am pumping air into the lungs, why a drop. My logic says not enough co2 is escaping the head piece and I am rebreathing my waste air. The pressure was originally set at 16, which caused a dramatic drop in my wellbeing. Head ache, stiff neck and 7 hours of sleeping in my chair. I dropped the pressure to 10 (my health worker was on vaca) and it is much better. Episodes went from .8 per hr to 1.2 per hr. How can this drop be explained?

93 to 95 is not any problem. But to give you any real answers we would need data. We get data from Oscar, it is a totally free download from the top of the site. You also need a SD card from 2 gb to 32 gb to transfer the data from the Cpap to a computer.

I realize that the oxygen numbers are in the normal range. It just puzzles me how the o2 can drop with added air.

It could be you still have Apnea events that aren't currently treated with whatever settings you're running. So it circles back to show the data via OSCAR.
