91% oxygen
(10-11-2014, 01:45 PM)Peter_C Wrote: I have had multiple PEs, multiple times, which creates 'scars' where the clots were. Because of this, my O2 numbers are not the greatest. I am an ex-smoker, but have no other pulmonary issues as of my testing last year.

At rest during the day, my oximeter shows 92-94. During exercise (fat guy, slowly becoming an ex-couch-potato) I drop into the high 80s, but recover under one minute. At night I bounce around 91-92, usually with 1-4 minutes under 88%.

I also had an anemia issue last DEC (hospital for a refill, then iron pills for 2 months) which caused all my numbers to drop 2-3 points.

It is perfectly normal for regular people to drop to the mid 90s at night. Staying at or below 90 most of the night, or a lot of time (talking 60+ minutes) below 88% during a night is time to see the Doc (what I've been told by all my various Docs...

Having had 3 PE's is certainly enough pulmonary issues I would think !

I drop down into the mid to high 80's while under exertion, and have a prescription for 2 liter's of O2 while I exercise or walk ect .. I was prescribed it when my O2 levels started dropping to 88% or less. My doctor said any thing below 88% is harmful to all of the major organ in ones body.
When O2 levels drop below 88% he said cells start to slowly die and the lower the more get into that condition.

I'm surprised your doctor hasn't prescribed O2 for you under certain conditions, especially with having had 3 PE's
