The Effect of Eucapnic and Isocapnic Volitional Hyperventilation Upon Breathlessness
Under given circumstances breathlessness increases with increasing ventilation, and is usually estimated with respect to the prevailing level of ventilation. Under normal reflex (medullary) control ventilation is set at a metabolically appropriate level; volitional (cortical) breathing allows inappropriate levels of ventilation. The role of such inappropriate ventilation in the generation of breathlessness has been previously addressed, but with conflicting results.
