we conclude that doxapram increases chemosensitivity to hypoxia and slightly increase chemosensitivity to hypercapnia , indicating its primary action being stimulation of peripheral chemoreceptors , and doxapram stimulates chemoreceptors little in patients with chronic bronchitis , whereas blunted hypoxic response in normal subjects could be increased markedly .
