title: [Effectiveness of using oxygen at different periods of increased atmospheric pressure action (experimental studies)].
abstract: The allowable value of nitrogen supersaturation was determined in 4 dogs during 219 experiments in a hyperbaric atmosphere (2 and 3 ata) which simulated diving. In the course of a 1-and 4-hour exposure of dogs to increased pressures of oxygen and an inert gas the allowable value may either decrease or increase. In order to increase the value, it is most effective and reliable to allow a 20-minute prebreathing of oxygen at 2--3 ata.
