Pulse Oximeter for Sport and Fitness Blood Oxygen Saturation (SpO2) and Pulse Rate (PR) Measurements Black with Lanyard

The finger pulse oximeter is an electronic device that measures the saturation of oxygen carried in your red blood cells without using needles or taking a blood sample. Our Pulse Oximeter provides the following measurements: - SpO2 (Oxygen Saturation): Oxygen level in the blood to indicate changes due to heart or lung function, oxygen use by your body, or altitude. - PR (Pulse Rate): Number of heart pulses per minute to indicate overall fitness or exertion levels at any time. The pulse oximeter uses a cold light source that shines a light through the fingertip, making the tip appear to be red. By analyzing the light from the light source that passes through the finger, the device is able to determine the percentage of oxygen in the red blood cell. An oxygen saturation (SpO2) level between 95% and 99% is considered normal for most healthy individuals. A level of 92% indicates a deficiency in oxygen reaching tissues in the body.
