in sixteen open-chested pentobarbital-anesthetized dogs they found that repetitive hypoxia of the left lower lobe ( lll ) ( group i = lll nitrogen ventilation , n = 8 ; group ii = lll absorption atelectasis , n = 8 ) caused the percentage decrease in the electromagnetically measured fraction of the cardiac output perfusing the lll ( qlll/qt ) to become progressively greater ( increased lll hpv ) through the first three hypoxic challenges in group i and through the first four hypoxic challenges in group ii .
