Introduction to parameter
Oxygen Saturation is a measure of the level of oxygen in your blood.
In healthy individuals the normal Oxygen Saturation range is from 97% to 99%.
Oxygen plays an important role in ensuring that your muscles, brain and other organs receive the energy they need to function. A Pulse Oximeter is used to measure the level of oxygen in your blood, that is, how much oxygen your red blood cells are carrying.
To measure your oxygen saturation level, you will need a Pulse Oximeter.

- After use, wipe the outside and inside of your device with an alcohol wipe.
