Saturation of Peripheral Oxygen (SpO2) is a measure of the percentage of hemoglobin saturated with oxygen and can be measured by oximetry or through blood tests.

The body needs there to be a certain level of oxygen in the blood or it will not function as efficiently. In fact, very low levels of SpO2 can result in very serious symptoms. This condition is known as hypoxemia.

There is a visible effect on the skin, known as cyanosis due to the blue (cyan) tint it takes on.

Hypoxemia (low levels of oxygen in the blood) can turn into hypoxia (low levels of oxygen in the tissue). This progression and the difference between the two conditions is important to understand.
