Ventilation and Perfusion Ratios for Optimum Gas Exchange
... Ventilation and Perfusion Ratios for Optimum Gas Exchange Ventilation/perfusion ratio is the ratio of alveolar ventilation V to perfusion (pulmonary blood flow)Q. – In healthy lungs, the V/Q ratio is close to 1:1, resulting in optimum gas pressures and oxygenation in systemic arterial blood.
