What is considered a normal oxygen saturation range in healthy individuals?

Normal oxygen saturation shows how much of the hemoglobin is carrying oxygen. In healthy adults at sea level breathing air, arterial blood is normally nearly fully saturated, giving a pulse oximetry reading in the mid-90s to 100%. This range indicates adequate oxygen delivery to tissues at rest. Readings below about the mid-90s raise concern for hypoxemia or measurement issues, while readings in the high 90s to 100% are typical and reassuring. The 95-100% window best represents the standard normal range for healthy individuals.
