[Exercise tests in pneumology. C.R.E.D.O].
Exercise tests have proved very useful in numerous areas such as sports medicine, research, clinical medicine and rehabilitation to exercise and therapeutic trials. It is not always easy for a pneumologist to decide what sort of effort and which protocol to use. There is also the question of which parameter to use and the relationship between parameters and which are the most pertinent as a function of the aim of the research. Above all the exercise test should be adaptable in view of the diversity of the objectives. In routine pneumology the exercise test using a bicycle ergometer and a triangular type of protocol are recommended for numerous reasons. The usual parameters (ventilation, oxygen consumption, production of carbonic dioxide, cardiac rate and blood gases) and their derivatives all have a value in the domain of cardiorespiratory physiology. It is important in clinical practice not to give too great an emphasis to the exact relationship expressed as a function of the workload, because the cycloergometer is practically never calibrated or even checked by the user. Dyspnoea was the major symptom leading the patient to seek a consultation and it is of primary importance that all effort tests include an estimation of the sensation of breathlessness.
