A Diving rebreather is an underwater breathing apparatus that absorbs the carbon dioxide of a diver's exhaled breath to permit the rebreathing (recycling) of the substantially unused oxygen content, and unused inert content when present, of each breath.
The Savox was an oxygen rebreather with a use duration of 45 minutes. It had no hard casing and was worn in front of the body. [16] Siebe Gorman Salvus – Industrial rescue and shallow water oxygen rebreather; Siebe Gorman Proto – Industrial rescue rebreather set; IDA71 – Russian military rebreather for underwater and high altitude use ...
Underwater breathing apparatus can be classified as open circuit, semi-closed circuit, (including gas extenders) or closed circuit (including reclaim systems), based on whether any of the exhaled gas is recycled, and as self-contained or remotely supplied (usually surface-supplied, but also possibly from a lock-out submersible or an underwater habitat), depending on where the source of the ...
[3] [4] The inert gas and unused oxygen is kept for reuse, and the rebreather adds gas to replace the oxygen that was consumed, and removes the carbon dioxide. [3] Thus, the gas recirculated in the rebreather remains breathable and supports life and the diver needs only to carry a fraction of the gas that would be needed for an open-circuit system.
non-rebreather mask A non-rebreather mask (NRB) is a device used to deliver supplemental oxygen to a spontaneously breathing person. An NRB allows the delivery of relatively high concentrations of oxygen while using a constant flow rate, with relatively low waste, by accumulating the oxygen flow during exhalation in a soft bag, to be inhaled at ...
High altitude breathing apparatus is a breathing apparatus which allows a person to breathe more effectively at an altitude where the partial pressure of oxygen in the ambient atmospheric air is insufficient for the task or to sustain consciousness or human life over the long or short term.

The Oxygen breathing apparatus (OBA) is a closed circuit oxygen rebreather. used primarily in firefighting by the US Navy. Its oxygen is generated by chemicals contained in the green canister, which is inserted at the base of the breathing device.
