Liquid oxygen is the name of a product that is a solution of hydrogen peroxide [1] and other compounds including sodium chloride (common salt) [2] [3] that claims to help with "jet lag, fatigue, altitude sickness, headaches, hangovers, youthful skin, energy, and insomnia".
The capsule of Sarco provides for a rapid decrease in oxygen level while maintaining a low level of carbon dioxide. On activation, 4 litres (1.1 US gal) of liquid nitrogen causes the oxygen level to drop silently to less than 5% in less than one minute. According to Nitschke: "The occupant presses the button and the capsule is filled with nitrogen.
Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (14.5 psi).
Inventor of the Clark oxygen electrode Leland C. Clark Jr. (December 4, 1918 – September 25, 2005) was an American biochemist born in Rochester, New York. [ 1 ] He is most well known as the inventor of the Clark electrode , a device used for measuring oxygen in blood, water and other liquids. [ 2 ]
Wikipedia:Please do not bite the newcomers, a guideline, advises Wikipedia users to consider the obvious fact that new users of Wikipedia will do things wrong from time to time.

Medical oxygen storage tanks at the Royal Women's Hospital, Melbourne, Australia. Oxygen may be used for patients requiring supplemental oxygen via mask. Usually accomplished by a large storage system of liquid oxygen at the hospital which is evaporated into a concentrated oxygen supply, pressures are usually around 345–380 kPa (50.0–55.1 psi), [1] [2] or in the UK and Europe, 4–5 bar ...
[5] [17] Forensic death investigations of cause and manner of death may be very difficult when people die by suicide in this manner, provided the apparatus (such as the bag, tank, or tube) is removed by someone after death. [4] [17] Petechiae, which are often considered a marker of asphyxia, are present in only a small minority of cases (3%). [40]
[1] [23] The ability to combine N 2 O and oxygen at high pressure while remaining in the gaseous form is caused by the Poynting effect (after John Henry Poynting, an English physicist). [1] The Poynting effect involves the dissolution of gaseous O 2 when bubbled through liquid N 2 O, with vaporisation of the liquid to form a gaseous O 2 /N 2 O ...
