I recently got an oximeter, and have been monitoring my O2 levels. While exercising, I stay above 96. Normally during the day (sitting, walking, etc.) I stay between 94-96. At night while sleeping I seem to fluctuate between 90-93. My heart rate while sleeping is anywhere between 48-60.
Are my O2 levels while sleeping something to worry about?
Im 32, in generally good health, dont smoke, rarely drink, no caffeine. I've been getting treatment for a herniated disc in the neck (decompression), and have been diagnosed several times in the past few months with Costochondritis. I occasionally (once every few weeks) have shortness of breath issue during the day (the reason I got the oximeter).
I have a physical scheduled in the next few weeks, I just want to be prepared with good questions.
