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.

[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 ...
Pulse oximetry uses two light emitting diodes (LEDs), one red and one infrared, to measure the absorption of light and translates that into the percentage of hemoglobin molecules that are bound to oxygen, which is called arterial oxygen saturation (SpO 2). Conventional pulse oximetry assumes that arterial blood is the only blood moving ...
