A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements.

Pulse oximetry is a method used to estimate the percentage of oxygen bound to hemoglobin in the blood. [10] This approximation to SaO 2 is designated SpO 2 (peripheral oxygen saturation). The pulse oximeter is a small device that clips to the body (typically a finger, an earlobe or an infant's foot) and displays its reading, or transfers it to ...
Masimo Corporation is a health technology and consumer electronics company based in Irvine, California.The company manufactures patient monitoring devices and technologies, including non-invasive sensors using optical technology, patient management, and telehealth platforms.
Monitoring of vital parameters most commonly includes at least blood pressure and heart rate, and preferably also pulse oximetry and respiratory rate. Multimodal monitors that simultaneously measure and display the relevant vital parameters are commonly integrated into the bedside monitors in intensive care units , and the anesthetic machines ...
The Lifepak 15, 20/20e, 35 and CR2 include a CPR metronome that is also capable of verbally aiding rescuers in providing ventilations. Advanced Lifepak monitor/defibrillators also include options for synchronized cardioversion, external pacing, oxygen saturation monitoring, End tidal CO2, and both non-invasive and invasive blood pressure.

A conventional pulse oximeter monitors the perfusion of blood to the dermis and subcutaneous tissue of the skin. Finger pulse oximeter. With each cardiac cycle the heart pumps blood to the periphery. Even though this pressure pulse is somewhat damped by the time it reaches the skin, it is enough to distend the arteries and arterioles in the ...
