A pulse oximeter is a medical device used to measure the oxygen saturation level in the blood, typically clipped onto a finger. It also measures heart rate. It works by emitting light through the skin and measuring the amount of light absorbed by oxygenated and deoxygenated hemoglobin. This non-invasive device is commonly used in medical settings, as well as by individuals at home, especially those with respiratory conditions like COPD or asthma.
