I recently figured out how to add my Apple Watch SpO2 data to the sleep app Auto Sleep. Apple does not claim FDA approval accuracy of the O2 sensor. Often when I try to measure it on purpose with the watch the reading fails, so I don’t know that I can trust it when it records spontaneously.
Last night the Blood oxygen app reported my O2 ranging from 85 to 87% all night with an average of 86.0%. But my ahi was 0.3. And today it’s reporting my average awake O2 as 92%. My doctor wanted to hospitalize me when I had pneumonia and it fell below 92%. But I generally run a little low all the time and I’m not bothered by it at all.
I feel fine. I have a finger pulse oximeter and when I compare them they often match but sometimes they are within 1-2% either way (which seems like a lot when normal BO level is a fairly narrow range). I am rarely over 96% and tend to run 94-96 when awake. I don’t have a recording meter, unless you count the watch.
Since I just started adding that data to the sleep app I don’t have a trend. Before adding it to the sleep app I’d have a random low reading during the day when I was awake and felt fine, but the overnight measurements were fine.
Anyone else using the watch and AutoSleep app? Any thoughts?
My sleep maintenance is lousy. Occasionally I take half a THC gummy (after 62 years of clean living I’ve become a “user”
) which helps, but haven’t had any in the past week.
. My watch usually shows my nighttime O2 ranging from 88%-96% which is lines up with overnight oximetry my doc has ordered in the past. When I’ve checked the watch against an oximeter it’s always been within 1%. One important thing I’ve found is to make sure your band is tight enough to keep the watch from moving around to much, but not so tight that it cuts off circulation. Also important to note that the Applewatch only occasionally checks O2 throughout the night, so it doesn’t give as full of a picture as a recording oximeter. The range of 85-87% it’s showing for you is low, it’s good you plan to check your O2 with a recording oximeter. I also use the AutoSleep app, i find it gives you a decent overall representation of your sleep, but definitely not completely accurate. Every now and again a pack of coyotes hangs out in our yard howling all night which makes my dogs go crazy. On most of those nights my watch shows me as asleep during all the ruckus (I wish) my guess maybe it thought I was still asleep because I didn’t move around.
