BLOOD VOLUME IN PULMONARY TUBERCULOSIS
Archives of Internal Medicine, 1951THERE is only one report in the literature regarding the blood volume in pulmonary tuberculosis. Allbritten and co-workers, 1 using the Evans blue dye method, found that in 10 patients there was an average reduction in blood volume of approximately 15 per cent.

Pulmonary Capillary Blood Volume in Emphysema
American Review of Respiratory Disease, 1990Abstract We determined single breath diffusing capacity (DlCO) and pulmonary capillary blood volume (Vc) in a total of 110 patients, who were being evaluated for resectional lung surgery for a localized tumor or lesion. Pathologic assessment of emphysema was obtained in 55 cases who had resection of a lung or an upper lobe, based on a

Effects of Catecholamines on Pulmonary Blood Volume
Acta Physiologica Scandinavica, 1967AbstractThe effect of arterially injected adrenaline and noradrenaline on lung blood volume has been examined in isolated, blood‐perfused lung preparations from rabbit and cat. Both substances caused rapid and relatively marked reductions in the weight of the preparations, which was followed continuously.

Pulmonary Blood Volume in Chronic Bronchitis
Clinical Science, 19771. Pulmonary blood volume was measured in 39 patients with severe chronic bronchitis, of whom 29 had recently recovered from an acute exacerbation. Pa,o2 was below 10·3 kPa in all but five patients, Pa,co2 was above 5·6 kPa in 26 cases, and pulmonary artery mean pressure was above 20 mmHg in 29 cases. Pulmonary blood volume was measured with the double-

Continuous recording of pulmonary blood volume: pulmonary pressure and volume changes
American Journal of Physiology-Legacy Content, 1959A method for continuous recording of pulmonary blood volume in the intact animal has been devised, utilizing the detection of I131-tagged blood from a circumscribed portion of lung field. To rule out the interference of blood in the chest wall the counts per minute (cpm) obtained from the chest wall after removing the lung at the end of the experiment

Dehydration‐Induced Reductions in Total Blood Volume and in Pulmonary Blood Volume in Rats
Acta Physiologica Scandinavica, 1972AbstractGroups of rats were exposed to water deprivation and/or food deprivation for 24 h periods. The degree of dehydration obtained was evaluated by weight examinations of the differently treated rats. The plasma and erythrocyte volumes were estimated by the use of i.v. injected isotopes. It was found that on water deprivation the intravascular fluid

Respiratory Effect on the Blood Volume of Pulmonary Capillaries
Journal of Biomechanical Engineering, 1988We measured the density variations of aortic blood from rabbits ventilated by a positive end inspiratory pressure of 6 mmHg or a negative box pressure of the same magnitude. When calculated from the density variations, the fluctuations in blood volume of the pulmonary capillaries within one cycle as induced by an intermittent positive pressure ...

Reduction in Pulmonary Blood Volume after a Blood Loss
Acta Physiologica Scandinavica, 1970AbstractThere is little information about the possible role of the pulmonary vascular bed as a variable blood depot. An evaluation of the degree of blood mobilization from this vascular compartment after a blood loss has therefore been attempted. Rats were given labelled erythrocytes and albumin, and immediately after a standardized blood loss the ...

European Heart Journal, 1984
We studied the effects of a chronic increase in flow and of chronic hypertension on regional pulmonary blood volume and extravascular lung density (lung tissue and interstitial water per unit thoracic volume) in one group of patients with intracardiac, left-to-right shunt and in another group with Eisenmenger's syndrome or primary pulmonary ...

Pulmonary Blood Volume and “Pulmonary Hematocrit” during Hypervolemia in Rats
Acta Physiologica Scandinavica, 1971AbstractIn rats erythrocytes and plasma albumin were labelled by radioisotopes, and circulatory arrest was then achieved by rapidly freezing the intact animal in liquid nitrogen. Pre‐mortal blood content in different organs could then be evaluated by measuring the radioactivity in tissue samples from the frozen animals.
