How does it work? How can you check your current health?
During a pulse oximetry reading, a small clamp-like device is placed on a finger, earlobe, or toe. Small beams of light pass through the blood in the finger, measuring the amount of oxygen. It does this by measuring changes in light absorption in oxygenated or deoxygenated blood. This is a painless process. Once the oximeter finishes its assessment, its screen will display the percent of oxygen in your blood coming from your heart—as well as your current pulse rate.
A standard finger oxygen monitor shows you 4 parameters: SP02, PR, PI, RR. These are 4 important data that can make a preliminary assessment of your health without having to go to the hospital
