Mean airway pressure typically refers to the mean pressure applied during positive-pressure mechanical ventilation. Mean airway pressure correlates with alveolar ventilation, arterial oxygenation,[1] hemodynamic performance, and barotrauma.[2] It can also match the alveolar pressure if there is no difference between inspiratory and expiratory resistance.[3]
