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]

   Many are battery-powered and simply need to be turned on and placed on your index finger. Pulse oximeters display two readings—one is SpO2, which is the oxygen saturation level in your blood ...

4. Photoplethysmogram - Wikipedia

   en.wikipedia.org/wiki/Photoplethysmogram

   [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 ...

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. Oxygen saturation (medicine) - Wikipedia

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

   Pulse oximetry is a method used to estimate the percentage of oxygen bound to hemoglobin in the blood. [10] This approximation to SaO 2 is designated SpO 2 (peripheral oxygen saturation). The pulse oximeter is a small device that clips to the body (typically a finger, an earlobe or an infant's foot) and displays its reading, or transfers it to ...

7. Oxygen saturation - Wikipedia

   en.wikipedia.org/wiki/Oxygen_saturation

   Dissolved oxygen levels required by various species in the Chesapeake Bay (US). In aquatic environments, oxygen saturation is a ratio of the concentration of "dissolved oxygen" (DO, O 2), to the maximum amount of oxygen that will dissolve in that water body, at the temperature and pressure which constitute stable equilibrium conditions.
