Gas blending for scuba diving (or gas mixing) is the filling of diving cylinders with non-air breathing gases such as nitrox, trimix and heliox. Use of these gases is generally intended to improve overall safety of the planned dive, by reducing the risk of decompression sickness and/or nitrogen narcosis , and may improve ease of breathing .
SDI's philosophy is to improve recreational scuba diving training, enhancing older diving practices by incorporating new diving technology and emphasizing safety. [8] The curriculum is set up to take divers from the beginner level to instructor level and structures its courses around a logged dive and specialty course approach. [ 9 ]
Hold mask in place with hand. Practice diving with no mask. [19] Spare mask in emergency spares for team. [19] Use of full face mask that is more securely attached to the head and tethered by the hose. [6] Buoyancy compensator blow-up. (uncontrolled inflation) Uncontrolled ascent with possible decompression problems Inflation valve stuck open.
Through-water voice communication equipment is also available for recreational diving, but requires full-face masks. [32] [33] Divers can use rope signals when connected to another diver, or tethered by either rope or umbilical. A few basic codes using "pulls" and "bells" (short tugs, grouped in pairs) are partly standardized.
Surface-supplied diver at the Monterey Bay Aquarium, Monterey, California US Navy Diver using Kirby Morgan Superlight 37 diving helmet [1]. Surface-supplied diving is a mode of underwater diving using equipment supplied with breathing gas through a diver's umbilical from the surface, either from the shore or from a diving support vessel, sometimes indirectly via a diving bell. [2]
Masks held in place by adjustable straps can be knocked off or moved from the correct position, allowing water to flood in. Half masks are more susceptible to this, but because the diver can still breathe with a flooded half mask this is not considered a major issue unless the mask is lost. Full-face masks are part of the breathing passage, and ...
Diving disorders, or diving related medical conditions, are conditions associated with underwater diving, and include both conditions unique to underwater diving, and those that also occur during other activities. This second group further divides conditions caused by exposure to ambient pressures significantly different from surface ...
Deployment of a single tethered scuba diver is a reasonably safe alternative to free-swimming buddy team diving. The tethered scuba diver is equipped with a full-face mask with voice communications, high capacity scuba air supply, and an independent emergency air supply.
