What have your O2 sat's been running to start with? You should always ask n know. Ask your Pulmonologist and see what they say. Judy
WOW! Not knowing you it could be anything. Good question to ask your Doctor!
I wish you well. Hope you are doing better. My oxygen drops to 88 at sleeping. Oxygen being blocked into my lung , red blood cells are high. All my blood work is high. Calcium , chlosterol . Red blood now sugar. I wonder if there is any thing I can have done for high red blood? I am on oxygen over night 1 unit. I take Trelegy .
