➡️ What Does a Pulse Oximeter Measure?
Pulse Oximeters measure the percentage of arterial oxygen primarily. In more precise terms, this is the amount of oxygen carried on blood hemoglobin. It’s known as SpO2. Another way to see the result as oxygen saturation. This is an expression of the ratio between oxygenated to de-oxygenated blood.

There are parameters that you get along the way once you measure oxygen saturation. Heart rate (HR) is automatically calculated alongside the percentage of oxygen. HR and SpO2 complement one another, and clinicians find this double parameter readout quite informative.
