  • It is expressed in terms of percentage (%) and indicates the maximum amount of oxygen that your blood can carry.

What is the normal level of SpO2?

The easiest way to measure SpO2 Levels is by conducting a test called “Pulse Oximetry” and this can be done by using a simple and inexpensive device called “Pulse Oximeter”. It is the most efficient method of measuring the Blood Oxygen Saturation Level since it is a fast and accurate method with a negligible error rate. Also, it is a painless method in comparison to a blood test which can be invasive and costly.
