Abstract
Intrapulmonary shunt measured in the sitting position by the O2 breathing method increased at total lung capacity in 7 of 8 patients with pulmonary arteriovenous fistulas. This may explain the clinically noted increased murmur over a fistula on inspiration. An increased intrapulmonary shunt at total lung capacity might suggest the diagnosis in equivocal cases and provide a convenient test follow-up after surgery.This publication has 1 reference indexed in Scilit:
