The analysis of the structure of chest injuries in peacetime and wartime was carried out; a statistical analysis of the staged treatment of patients with ongoing bleeding with a perforating wound of the lungs during the war in Afghanistan, armed conflicts in the North Caucasus and according to the case histories of patients of the clinic of military-field surgery. The structure of the life-threatening consequences of chest injuries during military conflicts included continuing bleeding developing in 22.5% of cases with a through wound of the lungs; in peacetime in 18.6% of cases. The medical and technical requirements for the method of stopping the ongoing bleeding with a through wound of the lungs are formulated. Biological models of ongoing bleeding with a through wound of the lungs have been developed to conduct tests of the developed method. A method of stopping continuing bleeding in case of through-and-through lung injury in accordance with medical and technical requirements has been developed. The high efficiency of the developed method of stopping bleeding in case of through lung injury was experimentally confirmed (6 figures, 4 tables, bibliography: 7 refs).
