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.

   Pulse oximetry is a noninvasive, painless test that measures the oxygen saturation level of your blood. Here’s how it works and what the readings mean.

4. Oxygen saturation (medicine) - Wikipedia

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

   Example pulse oximeter. 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 ...

   Under careful watch, UCSF researchers attach a variety of pulse oximeters to study participants’ fingers, then lower their oxygen levels to a point where the devices should signal a problem.

6. 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.

7. Polysomnography - Wikipedia

   en.wikipedia.org/wiki/Polysomnography

   Pulse oximetry determines changes in blood oxygen levels that often occur with sleep apnea and other respiratory problems. The pulse oximeter fits over a fingertip or an earlobe. Snoring may be recorded with a sound probe over the neck, though more commonly the sleep technician will just note snoring as "mild", "moderate" or "loud" or give a ...
