Simple spirometry includes forced vital capacity (FVC), graphed as either a time-volume curve or as a flow- volume loop, slow vital capacity (SVC), and maximum voluntary ventilation (MVV).
According to this classification system, COPD is present when: residual volume is > 140% predicted, functional residual capacity is >130% predicted, total lung capacity is >120% predicted, or maximum voluntary ventilation is <75% predicted.
Bone mineral density, pulmonary function test (PFT), maximum voluntary ventilation (MVV), maximal inspiratory pressure (MIP), and maximal expiratory pressure (MEP) measurements of both groups were performed.
Maximum Ventilatory Capacity and Vital Capacity The maximum breathing capacity (MBC) or maximum voluntary ventilation (MVV) is a measure of the capacity of a patient to ventilate the lungs as fast and as deeply as possible.
Wanke et al found, however, no changes in VC, forced expiratory volume in 1 second, or maximum voluntary ventilation in either the control group or the training group.
