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".
Liquid oxygen is the liquid form of molecular oxygen. It has a density of 1.141 kilograms per litre (71.2 lb/cu ft), 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 (15 psi).
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).
Fire-prevention systems which result in the oxygen content being less than 19.5% are not permitted for occupied spaces without providing employees supplemental respirators by federal regulation (OSHA) in the United States. [6] However, hypoxic air is considered by some to be safe to breathe for most people. [7]
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, underwater diving and industrial applications.

At 30 msw (4 bar), 2% by volume oxygen in the lung gas gives a P O 2 of 60 millimetres of mercury (80 mbar). At 10 msw (2 bar), for the same 2% oxygen, the P O 2 would be 30 millimetres of mercury (40 mbar), i.e. marginal. At the surface the same 2% oxygen drops to 15 millimetres of mercury (20 mbar), ignoring metabolic use. [3]
