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.

Oxygen compatibility is the issue of compatibility of materials for service in high concentrations of oxygen. It is a critical issue in space, aircraft, medical ...
Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F). Solid oxygen O 2 , like liquid oxygen , is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum.
Oxygen transmission rate (OTR) is the measurement of the amount of oxygen gas that passes through a substance over a given period. It is mostly carried out on non-porous materials, where the mode of transport is diffusion, but there are a growing number of applications where the transmission rate also depends on flow through apertures of some description.

'red') is an oligomeric protein responsible for oxygen (O 2) transport in the marine invertebrate phyla of sipunculids, priapulids, brachiopods, and in a single annelid worm genus, Magelona. Myohemerythrin is a monomeric O 2-binding protein found in the muscles of marine invertebrates. Hemerythrin and myohemerythrin are essentially colorless ...
Temperatures on the order of 10 9 kelvins are needed to fuse oxygen into sulfur. [11] An atomic mass of 16 was assigned to oxygen prior to the definition of the unified atomic mass unit based on 12 C. [12] Since physicists referred to 16 O only, while chemists meant the natural mix of isotopes, this led to slightly different mass scales.
The Vietnamese government often groups the various provinces and municipalities into three regions: Northern Vietnam, Central Vietnam, and Southern Vietnam.These regions can be further subdivided into eight subregions: Northeast Vietnam, Northwest Vietnam, the Red River Delta, the North Central Coast, the South Central Coast, the Central Highlands, Southeast Vietnam, and the Mekong River Delta.
