What Is Pulse Oximetry?

A Pulse Oximetry in simple explanation, is a simple, non-invasive method of monitoring the percentage of a patient’s hemoglobin (Hb) which is saturated with oxygen (oxygenation).

In many circumstance, the Pulse Oximetry data is necessary whenever a patient’s blood oxygenation is unstable and needs to be monitored closely, including intensive care, critical care and emergency areas of a hospital. However, if you need to perform simple Pulse Oximetry at home, you may do so with a Pulse Oximeter.

Note(s) :

Pulse Oximetry cannot determine the metabolism of oxygen or the amount of oxygen used by the patient. Hence for this purpose, it is necessary to measure the carbon dioxide (CO2) levels too.
