Pulmonary blood flow redistribution by increased gravitational force.

This study was undertaken to assess the influence of gravity on the distribution of pulmonary blood flow (PBF) using increased inertial force as a perturbation. PBF was studied in unanesthetized swine exposed to -Gx (dorsal-to-ventral direction, prone position), where G is the magnitude of the force of gravity at the surface of the Earth, on the Armstrong Laboratory Centrifuge at Brooks Air For...

Changes in Cerebrovascular Prostaglandins and Thromboxane as a Function of Systemic Blood Pressure Cerebral Blood Flow

Cerebrovascular concentrations of prostaglandin E (PGE), prostaglandin F2, (PGF2.), 6ketoprostaglandin F,a (6-keto-PGFma), and thromboxane B2 (TXB2) were determined over a blood pressure range of 17-117 mm Hg (induced by inflation of balloon-tipped catheters placed in the thoracic descending aorta and at the aortic root) in eight newborn piglets to assess the role of prostanoids in cerebral blo...

Redistribution of cortical blood flow during renal vasodilatation in dogs.

Regional redistribution of blood flow in the mature fetal lamb.

Observations on mature fetal lambs delivered under chloralose anesthesia showed that variations in arterial blood gas tensions, caused by ventilation with gas mixtures of differing composition, produced considerable changes in regional systemic blood flows measured with a cannulated electromagnetic flowmeter. Partial asphyxia was associated with a rise in arterial pressure and a reduction in fe...
