The mean airway pressure during mechanical ventilation can be estimated based on ventilator settings.
Parameters:
(1) peak airway pressure in cm H2O
(2) positive end-expiratory pressure (PEEP) in cm H2O
mean airway pressure in cm H2O =
= ((peak airway pressure) + (PEEP)) / 2
The mean airway pressure increases as PEEP is increased.
