[2] Aeris, Originally also a brand of American Underwater Products, founded in 1998, was merged with Oceanic in 2014. The Aeris brand covered a wide range of recreational scuba equipment, including regulators, dive computers, buoyancy ...
Rebreather diver with bailout and decompression cylinders. Scuba gas management is the aspect of scuba diving which includes the gas planning, blending, filling, analysing, marking, storage, and transportation of gas cylinders for a dive, the monitoring and switching of breathing gases during a dive, efficient and correct use of the gas, and the provision of emergency gas to another member of ...
In rebreather diving, the typical effective endurance of the scrubber will be half an hour to several hours of breathing, depending on the type and size of the scrubber, the absorbent characteristics, the ambient temperature and pressure, the operational mechanics of the rebreather, and the amount of carbon dioxide produced by the diver, which ...
In which pO 2 is the chosen maximum partial pressure in oxygen in bar and the FO 2 is the fraction of oxygen in the mixture. For example, if a gas contains 36% oxygen and the maximum pO 2 is 1.4 bar, the MOD (msw) is 10 msw/bar x [(1.4 bar / 0.36) − 1] = 28.9 msw.
[1] [2] [12] [13] A maximum oxygen partial pressure of 1.4 bar for the active sectors of the dive, and 1.6 bar for decompression stops is recommended by several recreational and technical diving certification agencies for open circuit, [14] and 1.2 bar or 1.3 bar as maximum for the active sectors of a dive on closed-circuit rebreather ...

The third quarter of 2024 saw an annualized GDP growth of 3.1%, revised up from 2.8%. This marked the strongest quarterly performance of the year. Personal spending increased at its fastest pace ...
Depth limit for a group of 2 to 3 French Level 3 recreational divers, breathing air. [17] 66 m (217 ft) Depth at which breathing compressed air exposes the diver to an oxygen partial pressure of 1.6 bar (23 psi). Greater depth is considered to expose the diver to an unacceptable risk of oxygen toxicity. [nb 2] 100 m (330 ft)
