[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.

Vestibular nystagmus under hyperbaric conditions.

Sixty subjects participated in 454 experiments, 94 of which involved a centrifuge and an overload of 2 units. The studies showed that otolithic stimulation (the 2 unit overload) either activated nystagmus or had no substantial effect on the magnitude of this property. The paper advances a new, supplementary method for individual evaluation of the functional state of the vestibular analyzer of a pilot, in complicated cases of vestibulometry in clinical examinations, by comparative evaluation of the intensity of the nystagmic response under normal and hyperbaric conditions. Patients in whom the nystagmic slow phase speed (SPS) during hyperbaria (2 units) exceeds its usual value are designated as vestibulo-resistant; persons in whom the SPS of the nystagmus does not change substantially during hyperbaria are designated as vestibulo-susceptible.
