Pulse Oximetry

Pulse oximetry is a non-invasive medical test used to measure the oxygen saturation level (SpO2) of a person's blood. It provides a quick assessment of how effectively oxygen is being transported throughout the body. The test typically involves the use of a device called a pulse oximeter, which is commonly attached to a fingertip, earlobe, or toe. The device uses light sensors to detect the color of the blood, which changes based on the amount of oxygen bound to hemoglobin.Pulse oximetry is widely used in various medical settings, including hospitals, clinics, and during home healthcare monitoring. It is particularly useful for patients with respiratory or cardiac conditions, as well as for assessing the effectiveness of supplemental oxygen therapy. It is considered a vital sign measurement alongside heart rate, respiration rate, and blood pressure.One of the advantages of pulse oximetry is that it is painless, quick, and can be performed with minimal training, making it an essential tool for healthcare providers to ensure adequate oxygenation of patients.
