During a pulse oximetry reading, a small clamp-like device is placed on a finger, earlobe, or toe. Small beams of light pass through the blood in the finger, measuring the amount of oxygen. It does this by measuring changes of light absorption in oxygenated or deoxygenated blood.What is a normal pulse oximetry reading?
Normal results on a pulse oximetry reading range between 96 and 100 percent of this maximum value. If your pulse oximetry readings fall below 90 percent of maximum, you enter a clinical state called respiratory failure, characterized by inadequate oxygen supplies to your vital organs and body tissue.
