Abstract
Introduction. One of the promising directions of creating fundamentally new submarines’ crews rescue methods is the usage of perfluorocarbon breathing fluids. The last study of liquid ventilation in hyperbaria was published in 1985. The current level of technology development open up new opportunities for the practical implementation of this direction. To determine further development direction of usage liquid ventilation technology and to understand the place of this technology in existing or prospective systems of assistance and evacuation from emergency submarines, it is necessary to analyze the causes of emergency situations on submarines and the conditions of fight for survivability. We devoted this study to determining possible scenarios for the use of liquid ventilation technology, as well as its place in the system of assistance and evacuation of crews of emergency submarines. We have devoted this study to determining possible scenarios for the use of liquid ventilation technology as well as its place in the system of assistance and evacuation of emergency submarines crews. The study aims to substantiate possible scenarios for the usage of liquid ventilation technology in the rescue of submarine crews in distress from an underwater position. Materials and methods. The following used materials were: publicly available literature data; regulatory documents defining the procedure for carrying out rescue operations in case of accidents on the submarine; own experimental data. The main research method was generalization and analysis. Results. The researchers have presented the analysis of literature data on accidents on submarines. There are three typical scenarios of the development of the consequences of accidents, each of which can be characterized by the impact of certain pathological factors on the body. We also have determined the frequency of their occurrence. The experts have presented the conditions of preliminary stay in the emergency compartment of the submarine, which directly determine the actions of the crew, as well as factors influencing the use of liquid ventilation technology and typical conditions for the use of the latter. The scientists have determined the conditions of preliminary stay in the emergency compartment of the submarine, which directly determine the actions of the crew, as well as factors influencing the use of liquid ventilation technology, and typical conditions for the use of the latter. The conditions for the use of liquid ventilation technology in case of accidents on the submarine are determined in accordance with possible scenarios. Conclusion. Methods of evacuation of crews from submarines using liquid ventilation technology can become a significant addition to the existing rescue system, expanding and opening up additional opportunities for rescue operations in conditions in which it is not possible to apply known methods.
