The efficacy of hyperbaric oxygenation in experimental and hemorrhagic shock

: The efficacy of hyperbaric oxygenation (HBO, 2 atm, 1 h, altitude chamber "Irtysh-MT") has been studied in acute experiments on 56 adult dogs with hemorrhagic and traumatic shock. It has been established that HBO has a marked therapeutic effect in hemorrhagic shock, especially in its early period, when almost all the animals are saved from death. In the late period of hemorrhagic shock and in the early period of traumatic shock HBO effect was manifested only in insignificant increase in the animals' survival and lifespan. In the late period of traumatic shock toxic effect of hyperbaric O2 application was observed and the majority of animals died before the end of HBO session.
