Summary
Oxygen saturation, or SpO2, is the amount of oxygen-carrying hemoglobin in the blood relative to the amount of hemoglobin not carrying oxygen.
1
The body needs a certain level of oxygen in the blood to function efficiently.
1
Blood oxygen levels are measured with a pulse oximeter, which clips onto a finger or other part of the body.
2
Normal arterial blood oxygen saturation levels in humans are 97–100 percent.
3
If the level is below 90 percent, it is considered low and called hypoxemia.
3
Low oxygen levels can lead to respiratory or cardiac arrest.
3
Oxygen therapy may be used to assist in raising blood oxygen levels.

Summary
SpO2, also known as oxygen saturation, is a measure of the amount of oxygen-carrying hemoglobin in the blood relative to the amount of hemoglobin not carrying oxygen. The body needs there to be a certain level of oxygen in the blood or it will not function as efficiently.

Summary
Your blood oxygen level is a measure of how much oxygen your red blood cells are carrying. Your body closely regulates your blood oxygen level. Maintaining the precise balance of oxygen-saturated blood is vital to your health.

Summary
Oxygen saturation is the fraction of oxygen-saturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the blood. Normal arterial blood oxygen saturation levels in humans are 97-100 percent, and if the level is below 90%, it is considered low and called hypoxemia. Oxygen saturation can be measured in different tissues, such as venous oxygen saturation, tissue oxygen saturation, and peripheral oxygen saturation, and is typically measured at a fingertip using a pulse oximeter.
