pulse oximeter
noun
plural pulse oximeters
: a noninvasive medical device that utilizes spectrophotometry to measure the oxygen saturation of circulating arterial blood in an individual by determining the percentage of oxygenated hemoglobin pulsating through a network of blood capillaries by way of a sensor attached typically to a finger, toe, or earlobe
Your pulse oximeter will give you a numerical reading—a percentage that indicates the level of oxygen saturation in your blood.—

pulse oximeter
noun
: a noninvasive medical device that utilizes spectrophotometry to measure the oxygen saturation of circulating arterial blood in an individual by determining the percentage of oxygenated hemoglobin pulsating through a network of blood capillaries by way of a sensor attached typically to a finger, toe, or earlobe
Note: The pulse oximeter typically sounds an alarm if the blood saturation becomes less than optimal.
Pulse oximeters measure hemoglobin oxygen saturation via an external probe. The light of two varying wavelengths passes through the skin, and the difference in absorbance by arterial blood of these two wavelengths by the photodetector within the pulse oximeter is used to calculate the level of oxygenation.—Pediatric Emergency Medicine Reports
