Regional pulmonary blood flow in patients with circulatory shunts.
Carbon dioxide labelled with oxygen-15 can be used to compare the blood flow in different regions of the lung. Results obtained with this technique in normal subjects at rest with the chest upright show that there is a much higher perfusion per unit of alveolar volume in the lower zone than in the upper zone. On moderate exercise the flow increases in both zones but the lower zone blood flow re...
متن کاملRegional Pulmonary Blood Flow
unteers were studied, nine sitting and seven supine. During hypoxia there was a slight but significant increase in relative perfusion of the upper portions of the lungs in both the sitting and supine subjects. During recovery from hypoxia, blood flow distribution differed significantly from the control. The erect subjects showed increased relative perfusion of the lung bases and the supine subj...
متن کاملAlterations in regional pulmonary blood flow in patients with congenital heart disease studied by radioisotope scanning.
External scintillation scanning of intravenously administered '31I-labeled macroaggregates of human serum albumin (1311-MAA) was employed to evaluate the distribution of pulmonary arterial blood flow in 61 normal subjects and in 100 patients with various congenital cardiovascular malformations. Intra-aortic administration of 131I-MAA demonstrated that blood flow through subelavian-pulmonary art...

Regional Cerebral Blood Flow in Patients With Hypertensive Intracerebral Hemorrhage • Regional cerebral blood flow was measured by Xe clearance method in 44 patients with hypertensive intracerebral hemorrhage (HIH) within three weeks from attack. Mean CBF in cases with the more disturbed consciousness was the lower value. There was no definite relationship between mean CBF and the duration from...
