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.

A more accurate value of systolic blood pressure can be obtained with a sphygmomanometer and palpating the radial pulse. [11] Methods using constitutive models have been proposed to measure blood pressure from radial artery pulse. [citation needed] The diastolic blood pressure cannot be estimated by this method. The American Heart Association ...
[1] [2] A PPG is often obtained by using a pulse oximeter which illuminates the skin and measures changes in light absorption. [3] 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 ...
