The original version of the game, now called Minecraft: Java Edition, is still modded this way, but with more advanced tools. Minecraft: Bedrock Edition, a version of the game available for mobile, consoles, and Microsoft Windows, is written in C++, and as a result cannot be modded the same way.
The density of the breathing gas is higher at depth, so the effort required to inhale and exhale (work of breathing) increases, making breathing more difficult and less efficient. [1] The higher gas density also causes gas mixing within the lung to be less efficient, effectively increasing the physiological dead space. [ 41 ]
The same depth change of 1 m upwards will increase the gas volume in the BC to 1.3/1.2 × 2.78 = 3.012 litres, a difference of 0.232 litres. Example 2: The same diver as in example 1 at 30 m depth at the beginning of the dive with 200 bar in the 12 litre cylinder has about 3.1 kg gas in the cylinder, requiring about 3.1 litres of gas in the BC ...
This limit is based on risk of central nervous system oxygen toxicity, and is somewhat arbitrary, and varies depending on the diver training agency or Code of Practice, the level of underwater exertion expected and the planned duration of the dive, but is normally in the range of 1.2 to 1.6 bar.

Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface breathing gas supply, and therefore has a limited but variable endurance. [1] The word scuba is an acronym for "Self-Contained Underwater Breathing Apparatus" and was coined by Christian J. Lambertsen in a patent ...
The usual meaning of diving helmet is a piece of diving equipment that encases the user's head and delivers breathing gas to the diver, but the term "diving helmet", or "cave diving helmet" may also refer to a safety helmet like a climbing helmet or caving helmet that covers the top and back of the head, but is not sealed.
Scuba diver of the late 1960s. The history of scuba diving is closely linked with the history of the equipment.By the turn of the twentieth century, two basic architectures for underwater breathing apparatus had been pioneered; open-circuit surface supplied equipment where the diver's exhaled gas is vented directly into the water, and closed-circuit breathing apparatus where the diver's carbon ...
As a person breathes, the body consumes oxygen and produces carbon dioxide. Base metabolism requires about 0.25 L/min of oxygen from a breathing rate of about 6 L/min, and a fit person working hard may ventilate at a rate of 95 L/min but will only metabolise about 4 L/min of oxygen [10] The oxygen metabolised is generally about 4% to 5% of the inspired volume at normal atmospheric pressure, or ...
