This action is required to retain the mouthpiece in place for the duration of the dive, and may strain the masticatory muscles or the temporomandibular joint, which is where the lower jawbone (mandible) hinges on the skull at the temporal bone. This problem can be aggravated by cold water, stress, and strong water movement, and can be reduced ...
A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.
Buddy breathing is a rescue technique used in scuba diving "out-of-gas" emergencies, when two divers share one demand valve, alternately breathing from it.Techniques have been developed for buddy breathing from both twin-hose and single hose regulators, but to a large extent it has been superseded by safer and more reliable techniques using additional equipment, such as the use of a bailout ...
Inspect external condition and test function before use. (specifically test the seal of exhaust valves and possible leaks in the second stage casing and mouthpiece before opening the cylinder valve). [24] Use equipment only if it is in good working condition. [5] Use of alternative air source if DV breathes wet during dive.
The findings of the 1977 report "Allergic reactions to mask skirts, regulator mouthpieces and snorkel mouthpieces" [16] encouraged diving equipment manufacturers to fit snorkels with hypoallergenic gum rubber and medical-grade silicone mouthpieces. For underwater swimming and diving, the side-mounted snorkel has long been the norm, although new ...
In a few models of full face mask a mouthpiece like those used on diving regulators is fitted, which has the same function as an oro-nasal mask, but can further reduce the volume of the external dead space, at the cost of forcing mouth-breathing. A smaller volume around the mouth increases distortion of speech.

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 ...
