The pulsatile nature of the pulmonary capillary blood flow.
The nature of the pulmonary capillary blood flow is fundamental for the understanding both of pulmonary hemodynamics and of respiratory gas exchange. Direct examinations of the surface of the lung in the cat, rabbit, dog and rat (1-5) have indicated that pulmonary capillary blood flow is basically non-pulsatile. On the other hand, experimental studies by Lee and DuBois (6), using the body pleth...

متن کاملPropagation of blood flow pulse in the normal human pulmonary arterial system. Analysis of the pulsatile capillary flow.
We studied a number of dynamic events associated with the pulsatile flow of blood in the pulmonary arterial system of six healthy men in the supine position. We used the nitrous oxide-body plethysmograph method to record the pulmonary capillary blood flow pulse and the phonocardiogram to determine the time of opening and closing of the pulmonary valve. The pattern of right ventricular ejection ...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Determination of the pulmonary capillary blood flow in man.
SEVERAL different methods based on respiratory maneuvers have been developed for the measurement of the rate of pulmonary capillary blood flow in man. These methods fall into two groups: (1) those involving the determination of the COo or 02 content of arterial and mixed venous blood from an analysis of alveolar gas—the first of these "indirect Pick methods" was developed by Loewy and von Schro...
