Pulse oximeter is a small medical device used for non-invasive measurement of peripheral blood oxygen saturation, pulse rate, and other indicators in the human body. It utilizes the different absorption rates of red and infrared light by oxygenated hemoglobin and reduced hemoglobin. The detector of the oximeter emits a light source, which changes the light absorption value after passing through Die Haut und das Blut . Die Daten werden dann von einem Mikrocomputer verarbeitet, um den Blutsaugensättigungswert des Blutes . zu erhalten
