[Study of the links between functional and clinical data in 212 asthma patients from 14 to 30 years old at a health spa in La Bourboule (author's transl)].

212 asthma patients, who attended their first health spa at La Bourboule, are studied. The functional data are statistically compared to those obtained from clinical examination. In this group of patients, it is found that: 1. Most of the functional tests are perturbed in proportion to the seiousness of the disease (determined by the number of days of attack per year). On the contrary, the other clinical criteria, and in particular the evolution time, do not affect the functional values. 2. The different ventilatory parameters studied are correlated two by two, for instance V 50 on the one had, FEV1, FEV1/VC or LR on the other. Finally the authors discuss the interest of V 50 and LR measurement in order to localize the bronchial obstruction in asthma at the level of either the large trunks (LR) or the small bronchii (V 50).
