What does it mean when my pulse Oximeter gives me two different readings in each hand? One gives 95 while the other gives only 90 !

Why I have two different readings of pulse Oximeter in each hand ?

One reads 95 , the other reads 90 only!

Same happens to me hope someone on here can give you the answer tried telling doctors but they don’t listen

Hi you have a dominant hand which is more active and gives you different readings as its warmer and has better circulation.

Also skin condition can prevent good readings hard calluses thickening of skin etc ...cold fingers causing poor perfusion ..

Hope that helps a little try warming your non dominant hand and retry but I would just go with the 95 and be happy... to increase readings do slow pursed lip breathing 💜💜

Blood pressure readings are the same they never match up with the other side 🙂

A spot on answer!

I've been wondering that too- thanks though I am left handed and my reading is always lower on the left hand?? xX

To be honest it can vary from finger to finger my above reply is about the only explanation for it ...due to my past career as a scrub nurse in theatres ...sometimes the pulse oximeter that works via infra red rays to detect the haemoglobin in the oxygen no finger will ever give you the same reading as your circulatory system moves around each digit...normally it wont work if fingers are cold or the oximeter is maybe dusty ...🧡🧡

Totally normal it also varies from finger to finger, I think it’s to do with the number of tiny blood vessels in each hand/finger which again vary
