    Breathing pattern and gas exchange at peak exercise in COPD patients with and without tidal flow limitation at rest

    Expiratory flow limitation (FL) at rest is frequently present in chronic obstructive pulmonary disease (COPD) patients. It promotes dynamic hyperinflation with a consequent decrease in inspiratory capacity (IC), Since in COPD resting IC is strongly correlated with exercise tolerance, this study hypothesized that this is due to limitation of the maximal tidal volume (VT,(max)) during exercise by the reduced IC, The present study investigated the role of tidal FL at rest on: 1) the relationship of resting IC to VT,(max) and 2) on gas exchange during peak exercise in COPD patients.
