Which of the following indicates normal oxygen saturation?

Normal oxygen saturation levels typically range from 93% to 100%. This range indicates that the hemoglobin in the red blood cells is adequately saturated with oxygen, which is crucial for the body's tissues to function properly. Levels below this range may suggest hypoxemia, which can lead to various health complications if not addressed.

In contrast, saturation levels that fall below 93% indicate the need for further medical evaluation, as they suggest insufficient oxygen reaching the body's tissues. Therefore, understanding the significance of oxygen saturation levels is essential for assessing a patient’s respiratory health and ensuring adequate oxygen delivery throughout the body.
