Arterial PO2 and arterial PCO2 do not change during exercise. This is surprising, since the obvious hypothesis to explain how ventilation increases in exercise is that a decrease in PO2 or an increase in PCO2 is sensed by chemoreceptors that tell the dorsal respiratory group that more ventilation is …

WebIncreased ventilation–perfusion heterogeneity, causing inefficient gas exchange, also contributes to the abnormal V′E/V′CO 2observed in cardiopulmonary diseases by increasing VD/VT.
