A member asked:
Can your blood oxygen level from your finger differ from your lower extremities?
10 doctors weighed in across 3 answers
Yes: Absolutely. Depending on the degree of vascular disease in your arms and legs, this can definitely vary. However it is less common to have vascular disease in your arms than in your feet. This is why oxygen levels in the fingers are most often more accurate than in the toes in people with vascular disease.
