What is Blood Oxygen?
Blood oxygen (SpO2) refers to the amount of oxygen carried in the blood.
It is an important parameter used in medical diagnostics and can be measured using a pulse oximeter or a smartwatch with built-in sensors. Typically, a normal SpO2 reading is between 95-100%, although it may vary depending on the person's age, health, and other factors. A low SpO2 level may indicate respiratory problems or other health conditions, and medical attention may be necessary. Some smartwatches include SpO2 monitoring as a feature to track and monitor fitness and wellness.
