pulse oximeter

pulse oximeter
pulse oximeter n a device that determines the oxygen saturation of the blood of an anesthetized patient using a sensor attached to a finger, yields a computerized readout, and sounds an alarm if the blood saturation becomes less than optimal
pulse oximetry n

* * *

an oximeter that measures the oxygen saturation of arterial blood by passing a beam of red and infrared light through a pulsating capillary bed, the ratio of red to infrared transmission varying with the oxygen saturation of the blood; because it responds only to pulsatile objects, it does not detect nonpulsating objects like skin and venous blood.
