Understanding Blood Oxygen Saturation
Blood oxygen saturation, or SpO2, is a measure of how much oxygen is present in the blood.
It is typically expressed as a percentage and is an important indicator of overall health.
Blood oxygen saturation is primarily affected by the amount of oxygen in the air we breathe.
For example, if you are in a high altitude environment with less oxygen in the air, your blood oxygen saturation will be lower than if you were in a low altitude environment with more oxygen in the air.
Additionally, certain medical conditions can make it difficult for the body to absorb and use oxygen, resulting in lower blood oxygen saturation.
The most common way to measure blood oxygen saturation is through a pulse oximeter, which is a small device that clips onto the finger and measures the amount of oxygen in the blood.
Smartwatches with built-in heart rate and SpO2 monitors use the same principle, but with a smaller sensor that is integrated into the watch itself.
The accuracy of smartwatch SpO2 readings can vary depending on a variety of factors, such as the type of watch, the placement of the watch, and the accuracy of the sensor used.
Additionally, movement can affect the accuracy of the readings, as the device may not be able to accurately detect the pulse when the user is moving.
That said, studies have shown that smartwatch SpO2 readings are generally accurate, and the data collected can be useful in tracking overall health trends.
