title: [Presence of the blood depot in orthostatic position and after physical exertion].
abstract: In healthy individuals and in patients with essential hypertension in the orthostatic position and on physical effort an insignificant reduction in the volume of the circulating blood and of the packed cell volume were in evidence; this being due to the outflow of the liquid part of the blood into the tissues. Even in instances of a well-marked orthostatic hypotonia, during medication with sympatholytic agents in particular, the circulating blood volume in the orthostatic position does not show any significant change. The results obtained by the authors and an analysis of the published data suggest that all of the blood is in circulation with none of it being repository or leaving the depot either in the orthostatic position or on physical effort.
