Lung blood flow studies in patients with scoliosis and neuromuscular weakness
Abstract
Pulmonary capillary blood flow was measured by the nitrous oxide body plethysmograph technique in 16 patients, 10 of whom had scoliosis and six neuromuscular weakness.
A linear correlation was found between the pulmonary artery to capillary flow conduction time and Pao2 (r=+0·85; p<0·001).
The finding of a reduced flow conduction time and its correlation with the Pao2 suggests the presence of pulmonary arterial hypertension presumably on the basis of active vasoconstriction.
