Pulse Oximeter

A pulse oximeter is a non-invasive medical device used to measure the oxygen saturation level in the blood. It works by emitting light through a person's finger or earlobe, and then detecting the amount of light that passes through to a sensor on the other side. The device then calculates the percentage of oxygen in the blood based on the amount of light absorbed. Pulse oximeters are commonly used in hospitals, clinics, and at home to monitor patients with respiratory or cardiac conditions, as well as athletes and pilots who need to monitor their oxygen levels during activity.
