Measuring Your Oxygen Level Today’s medical experts have access to a wide variety of SpO2 monitoring tools, including finger pulse oximeters. These compact, noninvasive devices attach painlessly to the fingertip and send wavelengths of light through the finger to assess SpO2 and pulse rate. Under...
Healthcare providers typically check blood oxygen levels through sensors called pulse oximeters placed on the skin. These sensors can work almost anywhere, but a sensor placed on your finger is the most common method. Generally speaking,pulse oximetersare accurate, but accuracy declines as your blo...
Measurement sitesDepending on the method, including wrist, finger, ear, neck, groin, popliteal fossa. Definition: What is the pulse rate? The pulse describes the mechanical and rhythmic expansion as well as contraction of the vessel walls caused by cardiac activity and the pressure wave triggered...
The measurement of oxygen saturation provides conclusions about the function of the lungs. By determining the saturation of the venous blood, the blood flow, oxygen uptake as well as metabolic activity of the tissue can be assessed. Peripheral oxygen saturation is also used to calculate arterial ox...
A variation of the light wave passing through the finger will give the value of the SpO2 measurement because the degree of oxygen saturation causes variations in the blood’s colour. This value is represented by a percentage. If your APK SpO2 Sensor says 98%, this means that each red blood...
