2. Pulse oximetry - Wikipedia

   en.wikipedia.org/wiki/Pulse_oximetry

   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.

   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 ...

   The pulse is the rate at which the heart beats while pumping blood through the arteries, recorded as beats per minute (bpm). [11] It may also be called "heart rate". In addition to providing the heart rate, the pulse should also be evaluated for strength and obvious rhythm abnormalities. [11] The pulse is commonly taken at the wrist (radial ...
