Mean airway pressure

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] There are several equations aimed at determining the real mean airway pressure.

[6] MAP is closely associated with mean alveolar pressure and shows the stresses exerted on the lung parenchyma on mechanical ventilation.

[7] In high frequency oscillatory ventilation, it has been suggested to set the mean airway pressure six above the lower inflection point on the lungs P-V curve.
