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.

   Follow these steps: Turn on the pulse oximeter and place it on your fingertip, ideally the middle or index finger. Sit still and avoid moving while the device reads your oxygen levels and heart ...

4. 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] A conventional pulse oximeter monitors the perfusion of blood to ...

5. 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 ...

   How to check blood oxygen using a pulse oximeter. Although they were scarce early in the pandemic, pulse oximeters are now easy to find. (An Amazon search returns 1,000 results.) Many are battery ...

7. 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).

8. Monitoring (medicine) - Wikipedia

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

   Monitoring (medicine) Display device of a medical monitor as used in anesthesia. A patient of an intensive care unit in a German hospital in 2015, with a monitoring screen displaying a graphical electrocardiogram, the heart rate and blood pressure all in real time. In medicine, monitoring is the observation of a disease, condition or one or ...

9. Pulse - Wikipedia

   en.wikipedia.org/wiki/Pulse

   In medicine, a pulse represents the tactile arterial palpation of the cardiac cycle (heartbeat) by fingertips. The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint (posterior ...
