Pulmonary vascular resistance and vascular transmural gradient

Journal of Applied Physiology, 1960
Perfusion studies were made on vascular beds of isolated dog lungs. Submerged, gas-free, fluid-distended lobes served for studies of resistance versus transmural pressure in a technique that abolished gravitational effects. Air-distended lobes with varying degrees of pulmonary edema were used to display the transmural gradient differences produced by ...

Vascular resistance in splenic perfusion

Journal of Surgical Research, 1968
Abstract Eighteen pig spleens have been perfused ex vivo, 9 each with heterologous and homologous blood. Angiographic evidence of spasm in the main splenic arteries probably caused the temporary early resistance to perfusion, with both homologous and heterologous blood.

Renal washout and vascular resistances

European Journal of Nuclear Medicine, 1987
Evaluation of the vascular transit through a transplanted kidney depends on the convolution of the arterial bolus in the renal vasculature. In order to stress the importance of the renal artery, an example where a moderate stenosis resembled allograft rejection is given.

Pulmonary Vascular Resistance in Emphysema

Chest, 1994
To assess the hemodynamic effects of pulmonary microvasculature disruption in emphysema, we examined resting pulmonary hemodynamics and lung function in 12 carefully identified patients with type A chronic obstructive pulmonary disease. Individuals with respiratory muscle weakness and intercurrent infection were excluded.

HYPERTENSION AND COMPONENTS OF VASCULAR RESISTANCE

Clinical and Experimental Pharmacology and Physiology, 1991
SUMMARY1. In renal wrap hypertension in the rabbit and in essential hypertension in humans, non‐autonomic components of resistance are the major factors contributing to elevated blood pressure.2. The central nervous system plays an important role in moment to moment blood pressure control but is not responsible for maintenance of elevated pressure in ...
