I had an overnight pulse oxygen test recently and the results showed two periods of approximately 30 - 45 minutes where my blood oxygen level dropped into the mid 80s and even into the mid 70s. I had a nadir of 72%. I was diagnosed with central and obstructive sleep apnea and am compliant with my BiPAP machine and O2 concentrator w/ 2 liters of O2. What are the possible effects of 60 - 90 minutes of low blood oxygen? Is this dangerous? Why would my blood oxygen level drop despite using BiPAP and O2?
Thanks so much for the advice. I am very relieved that the low oxygen level is not a problem. I will contact a sleep MD and try to get another sleep study done. In the meantime, I'll raise my O2 levels to 3 liters and see if that helps.
i recently had a sleep test done. along with apnea the doctor said my blood oxy levels were going down to 50%. he also noticed a slight dip during my stress test. im 40 years old and about 80lbs over weight. what are the side effects of low oxygen levels like this?
