Description
A pulse oximeter is a small, non-invasive device used to measure the oxygen saturation (SpO2) in a person’s blood and their heart rate. It works by emitting light through the skin, usually on a fingertip, and detecting the amount of oxygen in the blood based on the light absorption. Pulse oximeters are commonly used in hospitals, clinics, and home settings to monitor patients with respiratory or heart conditions, ensuring that they receive adequate oxygen levels. It’s a quick and easy tool to assess oxygen levels without the need for blood draws.
