Had the 2nd part of my sleep study last night. Had the mask on but even though I'm on oxygen 24/7 it was not added to the mask. Is that normal?
With the Cpap you may not need O2 for sleep. The positive air pressure may be helping you breathe deep enough you don't need the O2.
Strange because I didn't have oxygen at all.
when I had mine they reduced my oxygen until I started to dream and they turned it back up they said
