Field studies were conducted in a number of intertidal and offshore islands in the Persian Gulf between 2006 to 2013. SCUBA and skin diving surveys were conducted around Larak, Hormuz, Qeshm, Hengam, Farur, Kish, Lavan, Khark and Farsi islands in the northern region of the Persian Gulf. Marine invertebrates including nudibranchs were photographed up to 32 m. Several species of nudibranchs are r...

This study aimed to identify differences in personality characteristics related to decompression illness (DCI) in recreational scuba divers. A matched control group of nine divers (without DCI) and a research group of nine divers (with DCI) were recruited. Following a chamber dive (control group), or treatment for DCI (study group), three psychometric scales - Locus of Control, Eysenck's Person...

DESCRIPTION A 32-year-old scuba diver was admitted to the emergency department for distinct cutaneous lesions. Following an uneventful dive, his peers suspected of several lesions over his body pertaining to decompression sickness (DCS). After his initial assessment, he was referred to the underwater and hyperbaric medicine department for consultation. The patient was a senior diver and denied ...

OBJECTIVE To investigate the effect of scuba diving on the hearing threshold of sport divers who have no history of excessive noise exposure or of diving-related inner ear damage. DESIGN Cross-sectional controlled comparison study. SETTING General sports diving community. PARTICIPANTS Sixty sport divers with an average of 650 dives each and at least 4 years of diving experience (mean, 10 ...

The features of respiratory noises and fins for open-circuit scuba divers, indicating a multipole character emission, are specified in cameral conditions. It demonstrates possibility to detect low-frequency components with pressure gradient sensor near field. A estimating the rate an diver is demonstrated at distances up 100 m real sea. gives opportunity bearing (time delay pair hydrophones) by...

Exposure to increased pressure, such as that encountered under water, affects the mechanics of respiration and in particular, the behavior of the respiratory gases. Carbon dioxide plays a major role in the physiology of the high-pressure environment, since the increased breathing resistance easily leads to carbon dioxide retention. The latter has been observed frequently in scuba and helmet div...

Insulin-requiring diabetes mellitus (IRDM) is commonly described as an absolute contraindication to scuba diving. A 1993 Divers Alert Network survey, however, identified many active IRDM divers. We report on the plasma glucose response to recreational diving in IRDM divers. Plasma glucose values were collected before and after diving in IRDM and healthy control divers. Time/depth profiles of 55...
