Previous investigators have suggested the existence of “CO2 sensors” in the lung and an important role of these receptors in detecting the increase in venous CO2 flux and in regulating ventilatory response to meet the metabolic demand during exercise (38). However, no direct and definitive evidence has been established in identifying the CO2 receptor in the lung.
