[Does airways obstruction in children with asthma bronchial persist in the symptomfree interval? (author's transl)]

There is no doubt that asthmatic attack is creating symptoms of long-lasting obstruction. In symptom-free period many functional tests are quite normal. The most distinct changes found in that period of the diseases are the loss of elastic recoil and a raise of static compliance. This suggests that obstruction of any part of the airways cannot persist over the period of attacks.
