[Effect of dihydroergotamine on pulmonary perfusion in acceleration stress (author's transl)].

Abstract

An orthostatic circulatory load of varying degree (1-4 G) can be simulated by means of a human centrifuge. This results in a partial shifting of the intrathoracic blood volume into the capacity vessels of the lower extremity. In the pulmonary region, this is associated with a decrease in perfusion from the apical to the basal segments, which can be… (More)
