Benefits Of Using A Pulse Oximeter

A pulse oximeter is a device that monitors the amount of oxygen (oxygen saturation) in the blood. The readings from pulse oximeters help doctors assess how well oxygen is being transported from the patient's heart to the extremities. In addition to measuring oxygen levels, pulse oximeters provide continuous monitoring of the patient's heart rate and produce a waveform that indicates the strength of the pulse. Pulse oximeters are used in clinics and hospitals and are also available for home use. The devices are small clips worn on the patient's finger, toe, or earlobe.
