Pulse Oximeter

A pulse oximeter is a non-invasive medical device used to measure the oxygen saturation level in a person's blood, as well as their pulse rate. It works by emitting light through a part of the body, usually a fingertip or earlobe, and detecting the amount of light that passes through. This information allows the device to calculate the percentage of hemoglobin in the blood that is oxygenated. Pulse oximeters are widely utilized in hospitals and clinics to monitor patients, especially those with respiratory or cardiovascular conditions, as they provide critical insights into a patient's oxygenation status. The readings can help healthcare providers make informed decisions regarding treatment and interventions, ensuring that patients receive the care they need in a timely manner.
