Relationship between the change in a) ventilatory and b) cerebrovascular responses in older healthy subjects (Older) and chronic obstructive pulmonary disease (COPD) patients during hyperoxic hypercapnia following vitamin C administration, according to lung function. Note the significant relationship between increasing disease severity (forced expiratory volume in 1 s (FEV1)) and a larger change in ventilatory, but not cerebrovascular, sensitivity after vitamin C infusion.
