    Pulse oximeters came along in the 1980s as an easy and painless alternative. The device shines a light through the fingertip, seeking out oxygen-rich blood.

  3. 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. [4]

    An obstacle was that the pulse of blood created a great deal of noise. Early devices tried to work around this by limiting measurement to the ear, and with other methods. Shortly after starting at Nihon Kohden in 1971, Aoyagi showed how to remove the noise from the measurement, leading to a practical and accurate measurement of oxygen in the blood.

    To perform the test, one set of electrodes are placed on viable tissue (e.g. the chest) as a control and a second set is placed around the tissue in question (e.g. legs or feet). The electrodes may mildly heat the skin to increase blood flow into the area. Oxygen may also be given to the patient to see if that increases oxygen levels in the tissue.

    [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 ...

  7. Capnography - Wikipedia

    en.wikipedia.org/wiki/Capnography

    One shortcoming of measuring pulse oximetry alone is that administration of supplemental oxygen (ie. via nasal cannula) can delay desaturation in a patient if they stopped breathing, therefore delaying medical intervention. Capnography provides a rapid way to directly assess ventilation status and indirectly assess cardiac function.
