Abstract
In patients with chronic obstructive pulmonary disease (COPD), exertional dyspnoea generally arises when there is imbalance between ventilatory demand and capacity, but the neurophysiological mechanisms are unclear. We therefore determined if disparity between elevated inspiratory neural drive (IND) and tidal volume (VT) responses (neuromechanical dissociation) impacted dyspnoea intensity...
Background and objective
The combination of both reduced resting diffusing capacity of the lung for carbon monoxide (DLCO) and ventilatory efficiency (increased ventilatory requirement for CO2 clearance [V˙E/V˙CO2]) has been linked to exertional dyspnoea and exercise intolerance in chronic obstructive pulmonary disease (COPD) but the underlying mechanisms are poorly understood. The current study...
