WebPURPOSE: Breathing Reserve (BR) is a parameter for evaluating ventilatory limitation to exercise during Cardiopulmonary Exercise Testing (CPET). It is obtained by subtracting Maximal Ventilation at peak exercise (VEmax) from Maximal Voluntary Ventilation (MVV). MVV used in calculating BR can be directly measured or calculated.
