Pulmonary function abnormalities in symptom-free children after bronchiolitis.
Twenty-three children less than 18 months old who had clinical and radiological evidence of bronchiolitis and remained symptom-free thereafter were studied to determine pulmonary function ten years later. Abnormal Pao2, Viso V and RV/TLC ratio were found in the majority of subjects, and 31.3% had abnormalities in all three tests; four and one-half percent had exercise-induced bronchospasm. These changes indicate a residual parenchymal or airways lesion following bronchiolitis.
