What is the normal pulse oximetry reading range for healthy individuals?

The normal pulse oximetry reading range for healthy individuals is 95% to 100%. This range indicates that the blood is adequately oxygenated, which is vital for the body's tissues and organs to function effectively. A reading below 95% may suggest some level of hypoxemia, or insufficient oxygen in the blood, which could warrant further assessment and potentially prompt medical intervention.

Readings exceeding 100% are not physiologically possible, as the hemoglobin in the blood can only carry a certain amount of oxygen. Thus, an ideal reading is within the 95% to 100% range, reflecting optimal oxygen saturation in healthy individuals.
