Hello all
Hope you are all doing ok. I have mild emphysema and also sleep apnea. I measure my oxygen levels every night, usually it stay above 90 most of the night, but sometimes it drop to about 88 for 10 minutes during a 7 hour sleep. It only goes down for up to 30 sek at the time. Is this normal?. Most of the night it is from 92-94.
