[Fatal accidents with compressed air diving equipment (author's transl)].

The post-mortem findings of 4 sport divers involved in accidents showed air embolism of the heart as well as 2 subcutaneous emphysemas of shoulder and neck. The lungs were distended and the viscera were hyperaemic. The pleura showed petechiae and small patchy hemorrhages. In microscopic examination foci of alveolar hemorrhages of the lungs and, occasionally, muscosal rupture of small branches of the bronchial tree and of the bronchioli could be determined. The most likely causes for the accidents are discussed and special attention is given to panicking under water.
