Pulse oximeter on the finger of a 67-year-old male patient. This device, also known as a blood oxygen meter, measures the pulse rate and oxygen concentration of the blood. It monitors the oxygen concentration by measuring the absorption of light as it passes through the fingertip. This patient is being assessed in their own home.
