Why do i get higher pulse oximeter readings from my fingers than my toes?

Varies: Sometimes it can be from a technical difficulty in getting a good reading in your foot, or there may be a reduction in blood flow to your legs, PAD is one potential cause of this. There is a test known as an ABI that is non- invasive and give further information about the blood flow into your arms and legs. I would discuss your question directly with your doctor.

Methodology...: Try comparing the readings of both fingers. Then compare the readings of both toes. I'm thinking there is calibration issue that is optimal on the finger.

My pulse oximeter readings get lower when my hands warm up. Being cooler causes higher readings even with SOB. I thought the cold caused lower SPO2?
