Pulse Oximeter

A Pulse Oximeter is a compact, non-invasive medical device designed to measure the oxygen saturation level (SpO2) in a patient’s blood, along with their heart rate. It works by emitting light wavelengths through a fingertip, ear lobe, or other vascular areas to detect the color change in blood caused by oxygenated and deoxygenated hemoglobin. The device then calculates and displays the percentage of oxygen in the blood, providing immediate feedback on respiratory and circulatory function.

Widely used in hospitals, clinics, and home care settings, pulse oximeters are essential for monitoring patients with respiratory conditions like COPD, asthma, or COVID-19, as well as during surgical procedures and recovery. Their portability, ease of use, and rapid results make them invaluable for athletes, aviators, and individuals managing chronic health issues. Modern models often feature LED displays, low-power alerts, and Bluetooth connectivity for data tracking. By enabling quick and accurate assessment of oxygen levels, pulse oximeters play a critical role in early detection of hypoxemia and ensuring timely medical intervention.
