Abstract

This paper describes 4 unfortunate accidents caused by the difference in pressure inside and outside the diver’s suit. The issues relate to diver crushing, caisson disease, too fast an ascent to the surface and hypoxia as a result of exhaustion of oxygen in the diving apparatus are explained. The mechanism of the diving injuries was analysed and methods of prevention of such incidents were suggested.

Abstract

Numerous research works indicate that staying in a hyperbaric environment is a stressor. We have undertaken studies using an animal model to determine the effect of hyperbaria on adrenocortical secretion and the level of adrenal ascorbic acid (a.a.a.). The research was conducted on 70 male hooded rats, which were divided into groups and subjected to hyperbaric air and oxygen at an overpressure of 1 and 3 atn, with some of the animals being additionally burdened with physical effort (swimming). It was found that short-term exposures (30 minutes) of rats to hyperbaric conditions caused a decrease in the content of a.a.a. With a prolonged (3-hour) exposure to 3 atm air the a.a.a. content returns to a normal level. A reduction in the a.a.a. content indicates the presence of stress in hyperbaric conditions in the rat, however, it does not allow to determine its intensity with the method used in the study.

Abstract

The authors examined 104 divers performing dives in water, 14 exposed to simulated conditions in decompression chambers and 11 control subjects. The average blood sugar reading before diving amounted to 100 mg% with readings of 101 mg% after diving, whereas in the control group these readings were 107 and 100 mg% respectively and in the group of simulated dives, 102 before and 106 mg% after the exposure. It was found that the diet applied ensured a sufficiently high level blood sugar level in the subjects to protect them against hypoglycaemia. Further research in decompression chambers is required.
