[Potential disturbance in the regulation of respiration during hyperbaric nitrogen narcosis].

In order to explore the possibility of disorders in the respiration regulation under conditions of hyperbaric nitrogen narcosis, experiments on 4 test subjects were carried out. Nitrogen narcosis was simulated by nitrous oxide. The ventilation increment was measured as a function of an increase of the hypercapnic stimulus. A combination of high degrees of hypercapnia and the narcotic effect may lead to ventilation inhibition and respiration disturbance.
