I must be a rare breed During two sleep studies they have never recorded my sats below 90%

[ohammersmith]

85 and I think maybe even 84 one night when my mask was leaking badly.

as low as 89-90 during the day sitting around.

usually is 95-96.

In my pre sleep study home oximetry I was below **% over 90 % of the night.
Doc ordered oxygen at 2 liters every night.
Started CPAP las weeke w pressure of 14 and 2 liters oxygen still.
Have discovered if I am not getting oxygen my brain wakes me up by making horribly nightmares that wake me.

My wrist unit might record one or two below 60% on a night. Checking 7 consecutive nights of sleep I spent about 10% of total sleep time below 88% without an ASV. If you factor in my pattern of an hour awake alternating with an hour in apnea, I could guess that while having apneas I might have been spending about 20% of those times below SpO2 88%.

My O2 bottomed out at 21 % . The respiratory nurse told me in her 25 years of work the lowest she had seen had been in the mid 40's . just stayed there for a few secs then back up to mid 90's
