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. [4]
If the pulse oximeter is attached without compressing the skin, a pressure pulse can also be seen from the venous plexus, as a small secondary peak. The change in volume caused by the pressure pulse is detected by illuminating the skin with the light from a light-emitting diode (LED) and then measuring the amount of light either transmitted or ...

Masimo Corporation is a health technology and consumer electronics company based in Irvine, California.The company primarily manufactures patient monitoring devices and technologies, including non-invasive sensors using optical technology, patient management, and telehealth platforms.
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 ...
He led the team of pulse oximeter engineers which later developed the Ohmeda Biox 3700 [3] which was widely used in the anesthesia market in the mid-1980s. The first commercially available oximeters were produced by Hewlett-Packard, and were large, cumbersome, and expensive. These devices were of limited value because they were largely focused ...
