I have trouble going to sleep. I have never felt rested after sleeping in amy entire life. I was told today I had 41 episodes of apnea while I slept and my O2 sats dropped to 82. I have been on oxygen while I sleep since lung surgery in 2008. So actually the 82 is good, since it used to drop to the 70's. I have copd. Is that 41 episodes average? Bad? not so bad?
