Outline some key mechanisms that permit the continued elevation in alveolar ventilation in the face of arterial hypocapnia
Arterial hypocapnia refers to the decrease in carbon dioxide in the the arterial blood. This cause a low partial pressure of CO2, leading to alkalosis and hypercalcaemia. It results in hyperventilation (rapid/deep breathing).
In order to counter hyperventilation, the body decreases ventilation by bronchoconstriction. For continued elevation in alveolar ventilation, the partial pressure ratios of oxygen and carbon dioxide should be even, and the body does so by decreasing the amount of oxygen absorbed (by bronchconstriction). Other such mechanisms of the body are bronchodilation, vasodilation and vasoconstriction.
