Most of the time I rip the mask off and fall back asleep unmonitored when these are happening, hence why my average doesnt stay higher. If she would have looked at the graphs she would have seen this. She said this is OK since it stops and my all around average is low. I said how do you know that? She said as long as you arent having constant events all night your ox levels are fine. I really wanted to ask her is she was psychic,lol. If I am having 15-30 minutes at a shot in the 60's my body is being tortured. She wouldnt even acknowledge that I mentioned that some nights I am as high as a 15 AHI over 6 hours. I am pretty concerned at her answers considering I had documented drops as low as 63% at my sleep study. Is there something I am missing?
Shell, maybe I am missing something here. But having had similar symptoms, I have to ask:
what makes you believe that your bad nights and apnea clusters are an indication of low oxygen level
Would the following be possible, as in my case:
- my O2 desats occur only when sleeping without a mask, not on CPAP
- the apnea clusters can be triggered by flow limitations, mask leakage, changing sleep state at onset, or going into REM sleep, turning from side sleeping to supine, etc. ... they're like a vicious circle, sometimes my S9 Autoset's compensation doesn't help ... and my cummulated nasal congestion wakes me up
- such clusters have been happening less and less lately
- what I have left to complain about is excessive sleep fragmentation, which nightly AHIs don't show ... but are visible to some degree in the detailed ResScan curves: flow, flow limitations, etc.
