The first basic rebreather based on carbon dioxide absorption was patented in France in 1808 by Pierre-Marie Touboulic from Brest, a mechanic in Napoleon's Imperial Navy. This early rebreather design worked with an oxygen reservoir, the oxygen being delivered progressively by the diver and circulating in a closed circuit through a sponge soaked ...
Many diving rebreathers are descended from it. However, there were earlier underwater uses of rebreathers: Davis Escape Set for use in emergency by submariners from 1927 onwards; Siebe Gorman Salvus invented in the 1900s and first used in mines and by firemen; The rebreathers used by the Italian Decima Flottiglia MAS frogmen in World War II
1772: the first diving dress using a compressed-air reservoir was successfully designed and built in 1772 by Sieur [16] Fréminet, a Frenchman from Paris.Fréminet conceived an autonomous breathing machine equipped with a helmet, two hoses for inhalation and exhalation, a suit and a reservoir, dragged by and behind the diver, [17] although Fréminet later put it on his back.
Sir Robert Davis, head of Siebe Gorman, improved the oxygen rebreather in 1910 [58] [59] with his invention of the Davis Submerged Escape Apparatus, the first rebreather to be made in quantity. While intended primarily as an emergency escape apparatus for submarine crews, it was soon also used for diving , being a handy shallow water diving ...
Bailout gas and bailout procedure are closely linked. The procedure must be appropriate for the gas supply configuration. Initial bailout to open circuit is often the first step, even when a bailout rebreather is carried, as it is simple and robust, and some time is needed to get the bailout rebreather ready for use.

A scuba set is characterized by full independence from the surface during use, by providing breathing gas carried by the diver. Early attempts to reach this autonomy were made in the 18th century by the Englishman John Lethbridge, who invented and successfully built his own underwater diving machine in 1715, but though the air supply was carried in the diving apparatus, it relied on surface ...
The Momsen lung was a primitive underwater rebreather used before and during World War II by American submariners as emergency escape gear. It was invented by Charles Momsen, who worked on it from 1929 to 1932. [1]
Shaw's first rebreather was an AP Inspiration closed circuit rebreather, with which he eventually dived to depths beyond its purported capability.This prompted him to not only purchase a Mk15.5 but to replace its analogue electronics with the digital ones of the Juergensen Marine Hammerhead, resulting in a specially modified POD designed to handle extreme pressures.
