in eight pentobarbital-anesthetized dogs , whose left lower lobe ( lll ) inspired oxygen concentration ( fio2 ) was constantly 0.21 , selective stepwise reductions in the rest of the lung ( rl ) fio2 from 1.0 to 0.15 caused the electromagnetically measured lll blood flow ( qlll/qt ) , pulmonary vascular resistance of rl ( pvrrl ) , and pvrlll to increase while rl pao2 , pao2 , pvo2 , and lll pao2 progressively decreased .
