We studied the effects of regional alveolar hypoxia on permeability pulmonary edema formation. Anesthetized dogs had a bronchial divider placed so that the left lower lobe (LLL) could be ventilated with a hypoxic gas mixture (HGM) while the right lung was continuously ventilated with 100% O2. Bilateral permeability edema was induced with 0.05 ml/kg oleic acid and after 4 h of LLL ventilation with an HGM (n = 9) LLL gross weight was 161 +/- 13 (SE) g compared with 204 +/- 13 (SE) g (P less than 0.05) in the right lower lobe (RLL). Bloodless lobar water and dry weight were also significantly lower in the LLL as compared with the RLL of the study animals. In seven control animals in which the LLL fractional inspired concentration of O2 (FIO2) was 1.0 during permeability edema, there were no differences in gravimetric variables between LLL and RLL. In eight additional animals, pulmonary capillary pressure (Pc), measured by simultaneous occlusion of left pulmonary artery and vein, was not significantly different between LLL FIO2 of 1.0 and 0.05 either before or after pulmonary edema. We conclude that, in the presence of permeability pulmonary edema, regional alveolar hypoxia causes reduction in edema formation. The decreased edema formation during alveolar hypoxia is not due to a reduction in Pc.
