The 13 pages that link to Ventilation–perfusion mismatch, each with the reason it gives.
Pulmonary edemaRelated: Edema creates poorly ventilated regions that may still receive blood flow.
Pulmonary alveolusRelated: Gas exchange depends on matching fresh alveolar air with perfusing blood.
Oxygen therapyRelated: It is a common cause of hypoxemia that often responds to supplemental oxygen.
Respiratory failureRelated: Uneven airflow and blood flow commonly impair oxygenation.
AtelectasisRelated: Atelectatic regions may remain perfused despite receiving little air.
