Diving disorders are medical conditions specifically arising from underwater diving. The signs and symptoms of these may present during a dive, on surfacing, or up to several hours after a dive. The principal conditions are decompression illness (which covers decompression sickness and arterial gas embolism ), nitrogen narcosis , high pressure ...
[2] [55] Evidence does not suggest that dysbaric osteonecrosis is a significant risk in recreational scuba diving. [53] Exposure to increased partial pressure of oxygen during diving can raise the level of oxidative stress in which increased production of free radicals can occur.
Nitrox and drysuit use, greater frequency of diving in the past year, increasing age, and years since certification were associated with lower risk, possibly as indicators of more extensive training and experience. [1] Statistics show diving fatalities comparable to motor vehicle accidents of 16.4 per 100,000 divers and 16 per 100,000 drivers.
[49] [50] Scuba divers can surface away from the boat and be unable to swim back against the current or wind. [51] Live-boating: Diving operations from a manually controlled vessel under way, which may use the propulsion system to maneuver during the dive, with associated hazards to the diver. The risk is greater with surface-supplied equipment ...
Words like Advanced and Master, used in the context of recreational certification, such as advanced open water diver, peak performance buoyancy, master scuba diver, or master scuba diving instructor are used to market further courses where performance- or evidence-based reasons for the description are dubious or lacking, and the minimum ...
Training for Olympic diving competition requires 10-meter diving facilities, which are scant in some parts of the world. For example, the Walter Schroeder Aquatic Center, built in 1979 as a YMCA facility, is one of only two Olympic-sized pools in Wisconsin that can host large events, and it is the only facility in the southeast Wisconsin region ...
Faulty diving equipment such as diving regulators, improper breathing techniques, or buddy breathing lead to the inhalation or aspiration of fine salt water droplets. The small size of the droplets allows them to reach the lower respiratory tract without significantly triggering the upper airway 's cough reflex , hence getting aspirated without ...
A dive center is the base location where recreational divers usually learn scuba diving or make guided dive trips at new locations. Many dive centers operate under the guidelines of ISO 24803, [ 1 ] in which case the facilities must meet the ISO minimum standard for a service provider for recreational diving.
