A gas extender is an apparatus for extending the endurance of a breathing gas supply, for example, by re-using some of the gas in a rebreather circuit.The term is relatively frequently applied to semi-closed rebreather systems, but is not used very often. [29] [30] [31] Compare with oxygen conserving device and demand pulse device
This is a list of gases at standard conditions, which means substances that boil or sublime at or below 25 °C (77 °F) and 1 atm pressure and are reasonably stable.
The exhaled gas from these devices is discharged to the environment, and the oxygen is lost, so they are less gas-efficient than closed circuit rebreathers, but do not have a carbon dioxide scrubber or counterlungs, which is a saving on weight and bulk, and make use of the oxygen available in the ambient air, so their efficiency is better at ...
Under hyperbaric conditions (pressures above normal atmospheric pressure), other gases such as nitrogen, and noble gases such as argon, krypton, and xenon become anaesthetics. When inhaled at high partial pressures (more than about 4 bar, encountered at depths below about 30 metres in scuba diving ), nitrogen begins to act as an anaesthetic ...
