Recurrent wheezing in the preschool child.
The bronchoconstrictor response to exercise was measured in 29 healthy children and in 23 children with recurrent wheezing attacks, using the Wright low-range peak flow meter and a modification of the forced oscillation technique. None of the healthy children showed significant change in airflow obstruction after a 6-minute run, whereas 20 of the 23 wheezy children showed a mean rise in total respiratory resistance of 65-5%. All 23 children showed a fall in airflow obstruction after inhaling salbutamol solution.
