Sitting in the docs surgery today and noticed a finger oximeter on the desk.
I asked him how accurate they are, and he said very accurate.
So he stuck it on my finger and it read 97. Then he stuck it on his own finger and it read 95. PMSL. But he explained if we both were to walk to the front door and back, his would be much the same while mine would drop down a lot. When I did the 6 min. walk test two months ago, my sats started at 97 and ended at 89. So quite a drop. Keith. Just wondering if I need to get one, or am I better off not knowing.
