Pulmonary vascular volume, resistance, and compliance in man.
V ARIATIONS in the volume of blood in the pulmonary vessels have been assumed to play a role in the physiology of the lesser circulation since the time of William Harvey,' but few measurements of the human pulmonary blood volume in vivo are available. This volume is an important variable in the hemo-dynamics of the pulmonary eirculation because of the relationships between volume, pressure, and...
متن کاملPulmonary vascular resistance.
where P represents the pressure gradient between the pulmonary artery and the pulmonary vein, F, the blood flow per unit time, and R. the vascular resistance. For a given pressure gradient and flow rate, R will be determined, among other things, by the physical dimensions of the chaniiels that the blood traverses. In a rigid hydraulic system this formula applies over a wide range of flow and pr...

reader for the subsequent complex terrain. The book includes chapters which catalogue topics such as efferent-afferent neuronal circuitry (M. Palkovitz and L. Zaborszky), limbic and brainstem connections (J. Sutin and R. McBride), and Golgi analysis of the major cell types in the hypothalamus (O. Millhouse). It includes a phylogenetic description of the hypothalamic monoamine and acetylcholines...
متن کاملPulmonary vascular permeability index should not be called extravascular lung water pulmonary blood volume ratio
evaluated the performance accuracy of three extra vascular lung water (EVLW) ratios in patients with shock at risk for or with acute lung injury (ALI). Th ey indexed EVLW to actual body weight (ABW), predicted body weight (PBW) and pulmonary blood volume (PBV), and confi rmed that all EVLW ratios were higher in patients with ALI and in non-survivors and correlated with respiratory parameters. A...
