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.

In 2012, Masimo received FDA 510(k) clearance for devices and sensors with labeling for screening newborns for CCHD. It marked the first time the FDA cleared specific labeling indicating the use of pulse oximeters, in conjunction with a physical examination, to screen newborns for CCHD. [23]
Example pulse oximeter. 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 ...
However, in cases of shock, hypothermia, etc., blood flow to the periphery can be reduced, resulting in a PPG without a discernible cardiac pulse. [7] In this case, a PPG can be obtained from a pulse oximeter on the head, with the most common sites being the ear, nasal septum, and forehead. PPG can also be configured for multi-site ...

LambdaNative has been used for a diverse range of medical applications, for example the Phone Oximeter, [4] a smartphone based low-cost pulse oximeter. The Phone Oximeter was selected as one of the ten innovations for 2015 to achieve the United Nations Millennium Development Goals to decrease maternal and child mortality.
