ETYMOLOGY
THE TERM “SCUBA" (AN ACRONYM FOR "SELF-CONTAINED UNDERWATER BREATHING APPARATUS") ORIGINALLY

REFERRED TO UNITED STATES COMBAT FROGMEN'S OXYGEN REBREATHERS, DEVELOPED DURING WORLD WAR II BY CHRISTIAN J. LAMBERTSEN FOR UNDERWATER WARFARE.

Слайд 3

DEFINITION
A FORM OF UNDERWATER DIVING WHERE THE DIVER USES A SELF-CONTAINED UNDERWATER BREATHING APPARATUS (SCUBA)

WHICH IS COMPLETELY INDEPENDENT OF SURFACE SUPPLY, TO BREATHE UNDERWATER.

RISKS
Decompression sickness and arterial gas embolism in recreational diving are associated

with certain demographic, environmental, and dive style factors. A statistical study published in 2005 tested potential risk factors: age, gender, body mass index, smoking, asthma, diabetes, cardiovascular disease, previous decompression illness, years since certification, dives in last year, number of diving days, number of dives in a repetitive series, last dive depth, nitrox use, and drysuit use. No significant associations with decompression sickness or arterial gas embolism were found for asthma, diabetes, cardiovascular disease, smoking, or body mass index. Increased depth, previous DCI and days diving were associated with higher risk for decompression sickness and arterial gas embolism. 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
