I'm curious as to how the oximeter really works - if you have poor circulation, will it not give accurate results?
My son's O2 has been checked on many machines and it goes very low, a lot. yesterday a nurse from the state came and did vitals and it was 61, but went up to 71. His Dr is ordering supplemental oxygen and he is also getting C-pap for sleep apnea. But I'm wondering if it's really that low a lot or just bad circulation? (He doesn't show distress but his Blood pressure goes very low - today 57/43 - or very high: 186/164 - and doesn't show any distress.) His hands are not cold when he has these numbers and have color, but still wondering.

Re: Oximeter--- circulation
Circulation can be a factor, but usually you can switch to a different finger to cross check. Most of the time a circulation problem is more local in the hand than global.
Another thing to consider is getting a reading from toes or an ear lobe.

SpO2 96+% and holding...
Re: Oximeter--- circulation
I've done different hands and fingers and the readings are usually the same... Haven't done the toe or ear though.
Re: Oximeter--- circulation
The oximeter works by shining a red light, and an infrared light through the skin, the ratio of the two colors that is received varies with the oxygenation of the blood.
Better oximeters give a readout of the perfusion index, which gives you an indication of the blood flow.
Try a toe.
