Definition: Pulse oximetry is a non-invasive method of determining oxygen saturation, or the oxygen level in the blood. It is measured by a disposable probe or sensor that is placed on the forehead, earlobe, fingertip or bridge of the nose, or a re-useable finger pulse oximeter monitor. Normal oxygen saturation levels range between 95% to 100%. Oxygen saturation levels in COPD are typically lower.

Pulse oximetry monitors are useful for monitoring supplemental oxygen therapy. Are you on supplemental oxygen? Compare Prices of pulse oximetry monitors. Learn more about the pros and cons of pulse oximetry.
