WebInterestingly, exercise does not cause hyperpnea as one might think. Muscles that perform work during exercise do increase their demand for oxygen, stimulating an increase in ventilation. However, hyperpnea during exercise appears to occur before a drop in oxygen levels within the muscles can occur. 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).
