What is Pulse Ox? Pulse Oximetry (or Pulse Ox, for short) is a noninvasive method used to measure the saturation of oxygen in the bloodstream. Compatible devices use a combination of red and infrared lights with sensors on the back of the device which can determine the percentage of oxygenated blood (SpO2%) available in your blood. This value should, in general, be 95% or higher in most settings but can be influenced by altitude, activity, and an individual’s health. Why Should I Be Interested in Pulse Ox Tracking?
