[Recompression therapy in diving accidents--introduction, indication].

We show that among the numerous complications which may arise during diving, two have to be considered very carefully, namely decompression sickness and arterial gas embolism, for if treatment is being done inadequately, these may lead to permanent disability. Diagnosis and treatment are described. In general, therapy is given in a hyperbaric chamber by pure oxygen, in a hospital with the relevant equipment. Nevertheless, it is of prime importance to give, already on the scene of the diving emergency, as soon as possible pure normobaric oxygen as respiratory gas.
