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. Masimo - Wikipedia

   en.wikipedia.org/wiki/Masimo

   Conventional pulse oximetry assumes that arterial blood is the only blood moving (pulsating) in the measurement site. However, during patient motion, the venous blood also moves, which can cause conventional pulse oximetry to under-read SpO 2 levels because it cannot distinguish between the arterial and venous blood. [11] [12]

4. 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 ...

5. Hypoxicator - Wikipedia

   en.wikipedia.org/wiki/Hypoxicator

   [citation needed] Pulse oximeters should be used to monitor the level of arterial oxygen saturation that is the basic measure of hypoxic training dosage. Good brands have pulse oximeters integrated into the system and the best hypoxicators are equipped with automated biofeedback hypoxic training control mechanisms.

   In an ideal world, doctors would gauge health risks by measuring exercise capacity, Angadi added, noting that it should be considered a “vital sign” like blood pressure, pulse rate, and ...

7. 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 ...
