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.

3. 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).

4. Talk:Pulse oximeter - Wikipedia

   en.wikipedia.org/wiki/Talk:Pulse_oximeter

   The term "blood gas monitor" is incorrect and confusing, so I moved this page to "pulse oximeter", which is a much more current term. I will adjust redirects. I don't think that the term "blood gas monitor" should redirect here, at least not with out clear information that pules oximeters do NOT measure blood gases.--

5. Monitoring (medicine) - Wikipedia

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

   Pulse oximetry which involves measurement of the saturated percentage of oxygen in the blood, referred to as SpO2, and measured by an infrared finger cuff; Capnography, which involves CO 2 measurements, referred to as EtCO2 or end-tidal carbon dioxide concentration. The respiratory rate monitored as such is called AWRR or airway respiratory rate)

6. Photoplethysmogram - Wikipedia

   en.wikipedia.org/wiki/Photoplethysmogram

   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 this pressure pulse is somewhat damped by the time it reaches the skin, it is enough to distend the arteries and arterioles in the ...

   en.wikipedia.org/wiki/Oura_Health

   A third-generation Oura Ring, with pulse detection sensors visible at the bottom. The company's main product is the Oura Ring, which collects health data from the wearer's finger like a regular activity bracelet or heart rate monitor.
