Hi,
I hope this is the right forum for this question.
A recent blood test showed that I am anaemic. My doctor sent me for a second set of blood tests, for which I’m awaiting results.
My mum has a pulse oximeter. I tried it a few days ago and the reading was 89%. Every day since, the reading has been similar, but only when I’m sitting down. If I walk around, the reading is normal at 96 or 97%. When I sit down again it drops one percent at a time back down to 89%.
My understanding is that oxygen should stay in the range of 95% - 100%, no matter what. If I’m anaemic, shouldn’t the reading be low no matter what I do? Why one rule for rest, and one for activity?
I would really appreciate someone’s informed knowledge on this.
Jules
