[Effect of an increased content of oxygen and carbon dioxide on vestibular resistance]

Forty-two experiments on 21 test subjects, aged 20 to 40, were carried out to study possibilities of increasing vestibular resistance. This was achieved by improving the cerebral blood supply of the subjects who used the breathing air of 40-43% oxygen, 2% carbon dioxide and nitrogen. The results were treated statistically. This breathing air proved to increase the resistance of the vestibular analyzer to adequate stimuli. It is recommended to use this breathing air consisting of 40-43% oxygen, 2% carbon dioxide and nitrogen to prevent motion sickness and to discontinue vestibulo-vegetative disturbances that may appear in people using different flying and ground vehicles.
