I have not been diagnosed yet, scheduled for latter this month. Recently went to the Dr. with oxygen saturation spiking problems during the day and elevated blood pressure. Dr. recommended a sleep study to see if I have apnea. I have a problem with spending so much money without knowing more. I purchased a ring type sleep monitor to track my O2 while sleeping and it gives me mixed results. One night I can have 200 O2 drops >4% other nights I may have few drops >4%. Does anyone diagnosed with apnea have similar variable O2 drops from night to night? Can apnea be detected if O2 levels stay above the 3% or 4% threshold during the sleep study? Thanks for any input...

I am not exactly certain, but apnea events could drop your O2. After all, apnea is breathing restrictions or stoppages for 10 or more seconds. It will likely make oxygen drop. So would hypopnea and flow limits.

It doesn't point to apnea specifically though. Other things may be in play, but again nothing definite. I am not saying you have anything, so I use me as an example. If I take my O2 reading with pulse/oxy meter I may see 92 or lower. I do have severe mixed apnea and COPD. Which caused my O2 to drop? Not sure due to not enough info is my guess.

My opinion is there's not enough blanks filled into the formula to tell us what the cause is. A sleep study may do that though.
