2. Electro-galvanic oxygen sensor - Wikipedia

   en.wikipedia.org/wiki/Electro-galvanic_oxygen_sensor

   An electro-galvanic fuel cell is an electrochemical device which consumes a fuel to produce an electrical output by a chemical reaction. One form of electro-galvanic fuel cell based on the oxidation of lead is commonly used to measure the concentration of oxygen gas in underwater diving and medical breathing gases.

3. Oxygen sensor - Wikipedia

   en.wikipedia.org/wiki/Oxygen_sensor

   There is a linear relationship between the oxygen concentration and the electric current. With a two-point calibration (0% and 100% air saturation), it is possible to measure oxygen in the sample. One drawback to this approach is that oxygen is consumed during the measurement with a rate equal to the diffusion in the sensor.

4. Portable oxygen concentrator - Wikipedia

   en.wikipedia.org/wiki/Portable_oxygen_concentrator

   Portable oxygen concentrator used with bottle humidifier. POCs operate on the same principle as a home concentrator, pressure swing adsorption. [6] The basic set up of a POC is a miniaturized air compressor, a cylinder filled containing the sieve, a pressure equalizing reservoir and valves and tubes.

5. Oxygen concentrator - Wikipedia

   en.wikipedia.org/wiki/Oxygen_concentrator

   An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream. They are used industrially, to provide supplemental oxygen at high altitudes, and as medical devices for oxygen therapy .

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. 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.
