If an alveolus is poorly ventilated, then the local compensatory response is Constrict blood vessels leading to the alveolus.
What is alveolar hypoxia?
- Alveolar hypoxia, or low oxygen partial pressures, causes pulmonary arterioles and, to a lesser extent, pulmonary venules to constrict, which is a physiological phenomena.
- Blood flow within the vasculature is redirected by pulmonary vasoconstriction from areas of the lungs with poor ventilation to areas with greater ventilation.
- A physiological mechanism called ventilation and perfusion (V/Q) matching occurs in the lung in an effort to efficiently connect oxygenated (ventilated) regions with regions with adequate blood supply (perfusion).
- Pulmonary vessels narrow in low-oxygen conditions in an effort to divert blood to the lung's better-ventilated areas.
