2024年6月13日 · Healthcare providers typically check blood oxygen levels through sensors called pulse oximeters placed on the skin. These sensors can work almost anywhere, but a sensor placed on your finger is the most common method.

Pulse oximetry is a noninvasive method for monitoring blood oxygen saturation. Peripheral oxygen saturation (Sp O2) readings are typically within 2% accuracy (within 4% accuracy in 95% of cases) of the more accurate (and invasive) reading of arterial oxygen saturation (Sa O2) from arterial blood gas analysis.

Pulse oximetry is a test used to measure the oxygen level (oxygen saturation) of the blood. It's an easy, painless measure of how well oxygen is being sent to parts of your body furthest from your heart, such as the arms and legs.

Basically, pulse oximetry is a painless, noninvasive method of measuring the saturation of oxygen in a person’s blood. Oxygen saturation is a crucial measure of how well the lungs are working. When we breathe in air, our lungs transmit oxygen into tiny blood vessels called capillaries.
