What are the pros and cons of pulse oximeters? When ought to pulse oximeters be used? What do certain pulse oximeter readings mean? How accurate are pulse oximeter readings? Pulse oximetry is a time period that incessantly appears online and in information reviews in reference to COVID-19. But what, exactly, is it? Basically, pulse oximetry is a painless, noninvasive technique of measuring the saturation of oxygen in a person_s blood. Oxygen saturation is a vital measure of how properly the lungs are working. Once we breathe in air, our lungs transmit oxygen into tiny blood vessels known as capillaries. In turn, these capillaries ship oxygen-rich blood to the guts, which then pumps it by arteries to the remainder of the body. Our organs want a continuing provide of oxygen to work correctly. When the capability of the lungs to transport oxygen into the blood is impaired, blood oxygen saturation declines, potentially putting our organs in hazard.
