What is the normal range for oxygen saturation levels in a healthy individual?

The normal range for oxygen saturation levels in a healthy individual typically falls between 93% and 100%. This range indicates that the blood is adequately carrying oxygen to the tissues of the body, which is essential for normal physiological function. Levels within this range suggest effective oxygenation and lung function, signaling that the body is receiving sufficient oxygen to meet its metabolic needs.

In contrast, lower levels of oxygen saturation could suggest respiratory issues or inadequate oxygen exchange in the lungs. Thus, understanding the normal range is critical for assessing patient health and determining the need for further intervention or monitoring.
