Pulse oximetry is a procedure used to measure the oxygen level (or oxygen saturation) in the blood. It is considered to be a noninvasive, painless, general indicator of oxygen delivery to the peripheral tissues (such as the finger, earlobe, or nose).
Pulse oximetry is a quick, noninvasive method of measuring oxygen saturation in the blood. Risks associated with pulse oximetry are minimal and rare. Prolonged application of the probe may cause tissue breakdown at the application site.Skin irritation may result from the adhesive used in adhesive-containing probes.ulse oximetry technology utilizes the light absorptive characteristics of hemoglobin and the pulsating nature of blood flow in the arteries to aid in determining the oxygenation status in the body.
