Abstract

Traditionally, ventilatory limitation to exercise is assessed by measuring the breathing reserve (BRR) [ie, the difference between minute ventilation at peak exercise and maximum voluntary ventilation measured at rest]. Recent studies have however, documented important abnormalities in ventilatory adaptation with a remarkable potential to limit exercise even in the presence of a normal BRR. Among these abnormalities is lung hyperinflation and expiratory flow limitation. This was documented by comparing tidal to maximum flow-volume loops (FVLs) collected throughout the test. In the present study, we wondered whether the advantages of using such a technique within the classic cardiopulmonary exercise test (CPET) might be obscured by the maneuvers interfering with the main functional parameters of the test, and eventually with interpretation of the CPET.
