Résumé : Unfortunately, the situation in the chronic lung diseases is highly complex. Dyspnea, which is often responsible for impeding the excertions of the patient with chronic lung disease - as pain impedes the exertions of the coronary patient - only allows a relatively maximal oxygen consumption. The techniques of extrapolation are not more permissible in pathological conditions. On the other hand, and it is here that the pneumatological problem is peculiar, the mechanisms subjacent to the diminution in physical capacity are complex, often intricate, and difficult to clarify. The term 'chronic pneumopathy' covers a large group of diverse physiopathological conditions which not only make the interpretation of results difficult but still do not permit the allotment of specific pictures for each of them. At the very heart of a clinical condition that is apparently well defined there may be numerous and diverse functional disturbances. Thus the introduction of exercise tests into pneumology - if it is felt to be necessary because of the insufficient predictive value of the functional tests in sleep, if worked out on their own - always delayed, and the literature only brings us into this sphere (by comparison with cardiology, for example) some fragmentary data, hitherto inadequate and often controversial.
