Assessing the SpO in a random population - Looking for the best among fingers.

Context: Pulse oximetry is one of the most revolutionary methods used to monitor the patients in the clinical setting, particularly intensive care and anesthesia. We usually use the index or middle finger to measure SpO values, but little is known about the inter-digital differences that exist between the fingers.

Aim: We aim to compare the peripheral capillary oxygen saturation among fingers of both hands.
