WebApr 1, 2024 · During hyperventilation, conversely, blood PCO2 quickly falls and pH rises because of the excessive elimination of carbonic acid. The oxygen content of blood, on the other hand, is not significantly increased by hyperventilation(hemoglobin in arterial blood is 97% saturated with oxygen during normal ventilation). Chemoreceptors 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.
