  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. [4]

  3. Photoplethysmogram - Wikipedia

    en.wikipedia.org/wiki/Photoplethysmogram

    A photoplethysmogram (PPG) is an optically obtained plethysmogram that can be used to detect blood volume changes in the microvascular bed of tissue. [1] [2] A PPG is often obtained by using a pulse oximeter which illuminates the skin and measures changes in light absorption. [3]

  4. CO-oximeter - Wikipedia

    en.wikipedia.org/wiki/CO-oximeter

    Finger tip carboxyhemoglobin saturation monitor.. A CO-oximeter is a device that measures the oxygen carrying state of hemoglobin in a blood specimen, including oxygen-carrying hemoglobin (O2Hb), non-oxygen-carrying but normal hemoglobin (HHb) (formerly, but incorrectly, referred to as 'reduced' hemoglobin), as well as the dyshemoglobins such as carboxyhemoglobin (COHb) and methemoglobin (MetHb).

    en.wikipedia.org/wiki/Electro-galvanic_oxygen_sensor

    Electro-galvanic fuel cell as used in a diving rebreather to measure the partial pressure of oxygen. Two oxygen cells as used by oxygen analysers for diving gas showing commonly used connectors. An electro-galvanic fuel cell is an electrochemical device which consumes a fuel to produce an electrical output by a chemical reaction.

  7. Oxygen saturation (medicine) - Wikipedia

    en.wikipedia.org/wiki/Oxygen_saturation_(medicine)

    At 1,600 meters' altitude (about one mile high) oxygen saturation should be above 92%. [11] An SaO 2 (arterial oxygen saturation) value below 90% causes hypoxia (which can also be caused by anemia). Hypoxia due to low SaO 2 is indicated by cyanosis, but oxygen saturation does not directly reflect tissue oxygenation. The affinity of hemoglobin ...

    The finger sensor in the picture on the blood gas monitor page appears to be upside-down; the wire should be trailing off the top of the finger, shouldn't it? (I'm no expert.) Peter 05:10, 20 September 2005 (UTC)

  9. Oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Oxygen_sensor

    An oxygen analyser for breathing gas mixtures for diving. The type of oxygen sensor used in most underwater diving applications is the electro-galvanic oxygen sensor, a type of fuel cell, which is sometimes called an oxygen analyser or ppO 2 meter. They are used to measure the oxygen concentration of breathing gas mixes such as nitrox and ...
