Submarine rescue decompression procedure from hyperbaric exposures up to 6 bar of absolute pressure in man: effects on bubble formation and pulmonary function.

Recent advances in submarine rescue systems have allowed a transfer under pressure of crew members being rescued from a disabled submarine. The choice of a safe decompression procedure for pressurised rescuees has been previously discussed, but no schedule has been validated when the internal submarine pressure is significantly increased i.e.

MRI features of spinal cord decompression sickness presenting as a Brown-Sequard syndrome.

Decompression sickness often manifests as central nervous system impairment. We report a 49-year-old woman who developed an unusual case of spinal cord decompression sickness presenting as complete Brown-Sequard syndrome. Initial MRI revealed increased signal intensity in the left side of the cervical cord at the level of C2-C3.

Descriptive epidemiology of 153 diving injuries with rebreathers among French military divers from 1979 to 2009.

Introduction: Rebreathers are routinely used by military divers, which lead to specific diving injuries. At present, there are no published epidemiologic data in this field of study.

Methods: Diving disorders with rebreathers used in the French army were retrospectively analyzed since 1979 using military and medical reports.

[Current management of diving-related spinal cord decompression sickness in 2010].

The outcome of spinal cord decompression sickness after scuba diving is unpredictable during the 24 first hours with a high risk of incomplete recovery. The treatment is defined on first aid normobaric oxygen when neurological symptoms occur, rehydration and prompt recompression in hyperbaric chamber. The presence of initial motor impairment, the aggravation of symptoms during the transfer to the hyperbaric facility and the emergence of sphincter dysfunction are predictive of poor prognosis whatever the treatment undertaken.

Bubble incidence after staged decompression from 50 or 60 msw: effect of adding deep stops.

Objectives: The French Navy uses the Marine Nationale 90 (MN90) decompression tables for air dives as deep as 60 msw. The resulting incidence of decompression sickness (DCS) for deep dives (45-60 msw) is one case per 3000 dives.

Methods: Three protocols with experimental ascent profiles (EAPs) were tested in the wet compartment of a hyperbaric chamber.
