A doctor routinely uses a pulse oximeter with hospitalized patients.
The unit interprets light absorption By measuring the light, the pulse oximeter determines the oxygenation of your blood.
When a doctor seeks pulse oximetry information, he or she wants to measure the level of oxygen saturation in the blood.
Light passes through the finger If your finger was not in the pulse oximeter, the light would easily travel from the generator to the detector.
If you must take multiple readings throughout the day, you might wish to purchase a unit you can wear.
