[Electromyographic activity of respiratory muscles under hyperbaric conditions].
Two subjects were exposed to neon gas mixture and two others--to helium one. Electromyographic activity of their breathing muscles differed between the two groups depending on both the gas mixture and the steps of compression. Obvious difficulties of breathing with the neon hyperbaric mixture were accompanied by depressing of the EMG amplitude, episodic breaches or hyperactivation of the EMG. The findings suggest a predominant role of the diaphragm activity in hyperbaric conditions.
