ObjectiveTo study the influence of bronchoalveolar lavage(BAL) on pulmonary physiological function and partial oxygen pressure(PaO2).MethodsPulmonary function and partial oxygen pressure were measured in 42 patients with interstitial lung disease (ILD) before and after BAL, 7 non-smoker volunteers as control group.ResultsVC% and FEV1% decreased significantly from (74 +/- 17)% to (64 +/- 19)% and from (72 +/- 9)% to (65 +/- 12)%, respectively. PaO2 decreased from(77 +/- 11) mm Hg to (63 +/- 11) mm Hg. The above parameters were also decreased in control group, but had no statistical significance.ConclusionPulmonary physiological function and partial oxygen pressure of patients with ILD are influenced by BAL process.
