Pulse oximeter
The pulse oximeter measures the oxygen content of blood. A small clip is put on a finger, toe, or earlobe. The light beam in the clip measures the oxygen of the red blood cells that move through the cells in the finger, toe, or earlobe. The machine puts this information into a digital readout.
The pulse oximeter often has an alarm for blood oxygen levels that fall below a safe level.
