The influence of the pulmonary arterial pressure on the pulmonary capillary venous pressure in man.
In two cases with a well-defined pulmonary capillary venous pressure pulse, the lobular pulmonary artery was occluded with a balloon while the pulmonary capillary venous pressure was registered. There was no change in the tracing obtained. In two other cases positive pressure respiration almost completely damped out the pulmonary capillary venous pressure variations, but the mean pressure remai...
متن کاملChanges in transmural central venous pressure in man during hyperventilation.
We demonstrated that large amounts of blood shift from the forearm veins during hyperventilation (2). If this effect were generalized in the periphery of the body the volume of blood in the central venous reservoir might increase. An increase in pressure in the central veins would be evidence to support this suggestion. The fall in peripheral venous pressure which occurs during hyperventilation...
متن کاملPulmonary capillary arterial pressure pulse in man.
In 1948, Hellems, Haynes, Dexter, and Kinney, using venous and arterial catheterization in dogs obtained pressure recordings from both sides of the pulmonary capillary bed. The method consisted in wedging the tip of a cardiac catheter into a small branch of the pulmonary artery and of the pulmonary vein respectively, and recording the mean blood pressures in the obstructed vascular bed distal t...
متن کاملRenal lymphatic function following venous pressure elevation.
The renal lymphatic system plays an important role in removing excess fluid from the kidneys. Unfortunately, the factors influencing lymphatic flow are difficult to measure. We used a simple model to represent renal lymphatics as a single pressure source (PL) pushing lymph through a single resistance (RL). In anesthetized dogs, we cannulated renal lymphatics and measured lymph flow rate (QL) as...
متن کاملFurther evidence that the pulmonary capillary venous pressure pulse in man reflects cyclic pressure changes in the left atrium.
In four cases of atrial septal defect and in one case of mitral stenosis, the pressure pulse was recorded in the left atrium, in the first four cases through catheters, and in the fifth through a needle introduced through the chest wall. The pressure pulse was compared with pulmonary capillary pressure recorded simultaneously or nearly so. Good agreement was found both in shape and height of th...
