title: [Rheographic study of the human cardiovascular system during a many-day exposure to high pressure].
abstract: A rheographic study of the cardiovascular system in a N2-O2 atmosphere at 5 ata showed significant changes in the regulation of the leg vascular tone of most test subjects at rest. The study did not reveal marked changes in the pulsed blood inflow to the brain and lungs at rest. After moderate and especially after heavy work changes in the blood inflow were more pronounced in the hyperbaric atmosphere than at 1 ata. During the exposure an increase in the vascular tone of the systemic and pulmonary circulation was noted.
