Cardiopulmonary exercise test (CPET) evaluates cardiorespiratory function in dynamic conditions, in contrast to static pulmonary function tests which can not reproduce the dynamic situation of an individual. Despite its complex implementation there has been growing interest in CPET in evaluating the mechanisms of dyspnoea With this respect dynamic flow/volume curve is useful in identifying expiratory airflow limitation and dynamic hyperinflation. Besides gas exchange analysis during exercise deepens the quality of information in that subject. Its utility for decision making in complex perioperative evaluation can not be overemphasized. Considering its high reproducibility, this method is a highly valuable tool in cardiac stress testing. Several publications in Cardiology emphasize its value in diagnosis, follow up, prognosis and enlisting for transplant in congestive heart failure. Remarkably useful are maximal and submaximal indices obtained during exercise, such as peak oxygen consumption among the maximals, and carbon dioxide equivalent and oxygen consumption at lactic threshold, among the submaximal indicators

Palabras clave : Cardiopulmonary exercise test; dynamic hyperinflation; perioperative evaluation; peak oxygen uptake.
