Requested by 1992peter. Peter is a young gifted piano player and has interests in medical devices especially oxygen-related ones. Introduce yourself to him.. He is awesome :-) His motto that he lives by : “If I can’t do great things, I’ll do things in a great way” www.youtube.com A pulse oximeter is a medical device that indirectly measures the oxygen saturation of a patient’s blood. It also alerts medical personnel when O2 saturation is getting low hence giving the proper care needed for the patient. Hope you learn something today! I do appreciate your thoughts and comments. -Riza
