Slightly low blood oxygen after stair running, is it normal?
I'm a hypochondriac and 30 years old. I'm more or less in good shape although I haven't performed any regular exercise other than walking the last 3 months. I used to do weight training regularly but I was getting close to finishing my Ph.D. so I stopped lately.
Anyway, because I'm a hypochondriac, I actually own a pulse oximeter even though no doctor actually recommended one to me. I sometimes get panic attacks, even during exercise sometimes, so I wanted to buy one and make sure that I'm not starving of oxygen, only feeling that I'm starving of oxygen during panic attacks. So I keep it with me when I go to exercising on the street as well. These days I'm trying some stair running even though I haven't done regular cardio in a year except walking. I can run maybe 60 steps of stairs in double steps (skipping one step) but then I get winded. The other day I tried one, and after making it to the top, I felt winded for almost 2 minutes. Although I haven't stopped walking or climbing stairs regularly during those 2 minutes. Unfortunately I didn't have my pulse ox with me so I couldn't measure my oxygen.
Today I climbed a steep street, like a 15 minute climb and a quite steep one, and during the climb I measured my pulse ox. Now, these finger oxymeters can't do decent measurements while you are on the move, so I was stopping on the way and measuring my pulse ox and then kept climbing.
Most of the time, the pulse ox reads 99-98% the moment I put it on after stopping the climb. But when I wait there standing, it drops to 95ish and then climbs again to 98ish and then I start climbing again. One time I saw it drop to 92% and then climb immediately to 99%.
Is this a cause for concern? I don't know how much my pulse ox is exactly during the climb due to inaccuracies of the meters but when I stop on the way and measure, it starts reading at really high, and then it drops slightly for a few seconds and then picks up again to the top. How low a pulse ox is normal during this kind of activity? My heart rate was 155-160 during this climb and my resting heart rate is 60-65.
