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.

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.
A woman wearing an oxygen mask. An oxygen mask is a mask that provides a method to transfer breathing oxygen gas from a storage tank to the lungs. Oxygen masks may cover only the nose and mouth (oral nasal mask) or the entire face (full-face mask). They may be made of plastic, silicone, or rubber.
A closed circuit oxygen rebreather is the most efficient in terms of oxygen use, but is relatively bulky and requires the use of a carbon dioxide absorbent, which must either be sufficient for the oxygen supply, or must be periodically replaced.
partial rebreather mask A partial rebreather mask is an orinasal mask used for oxygen therapy for people who are spontaneously breathing. It allows full flow from the reservoir bag during inhalation, but only allows exhaled gas from the anatomical dead space where no gas exchange has occurred to reenter the reservoir bag during exhalation, The ...
Oxygen rebreathers can also use less reactive scrubber absorbent which only removes carbon dioxide, but must then have an alternative supply of oxygen, usually compressed gas from a high pressure cylinder. Submarine escape sets had a mouthpiece, so the user had to also wear a noseclip to prevent breathing water through the nose. The endurance ...
[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.
The Clearance Divers Breathing Apparatus (CDBA) is a type of rebreather made by Siebe Gorman in England. The British Royal Navy used it for many years. [1] It was for underwater work rather than for combat diving. The main oxygen cylinders are on the diver's back. The oxygen cylinders at the front of the diver are for bailout.
