2022-5-8 · This type of hypoxemia is easily corrected with supplemental oxygen. Ventilation-Perfusion Mismatch (V/Q Mismatch) This occurs when there is an imbalance between lung ventilation and blood flow. Even in the normal lung, there is a V/Q mismatch. In an upright individual, the V/Q ratio is higher in the apices than at the lung base.
