Brief Summary:
Scuba diving with closed circuit gas rebreathers is currently booming Initially developed for professional and military diving this type of diving has become very successful in recreational activities
The possibilities offered by this equipment are immense and reduce the constraints of exploration time and depth More and more divers are seeking to reach depths previously considered unusual or inaccessible in recreational diving beyond 100 meters By pushing back these limits the diver is exposed to new risks which should lead to a reflection on the means of prevention and treatment in case of incident
The physiological repercussions of these deep dives are not well known During daily deep excursions in the 90-120 meter zone there is a significant reduction in vital capacity on leaving the dive which persists and worsens the following day
It seems necessary to confirm the importance of this impairment never documented before and to explore its mechanisms A better knowledge of this respiratory impact could allow to improve the prevention and the preliminary evaluation of the medical aptitude of these divers
