What is the normal range for pulse oximeter readings?

The normal range for pulse oximeter readings reflects the saturation of oxygen in a person's blood. A reading between 95% to 100% is considered optimal for healthy individuals, indicating that the blood is adequately oxygenated. This level ensures that the body's tissues receive the necessary oxygen for proper function.

Readings below this range may suggest potential respiratory or circulatory issues, as they indicate that the oxygen saturation is not at ideal levels. While readings may vary slightly among different populations and can be affected by various factors including altitude and temperature, the accepted standard for healthy individuals is within this 95-100% range. Therefore, the choice that specifies this range is the most accurate for assessing normal readings using a pulse oximeter.
