Driving pressure calculation: Pplat = 28 cmH2O, PEEP = 8 cmH2O. What is driving pressure?

Driving pressure is the pressure that actually inflates the lungs during a breath, defined as plateau pressure minus PEEP. With a plateau pressure of 28 cmH2O and a PEEP of 8 cmH2O, the driving pressure is 20 cmH2O. This value reflects how much elastic pressure the lung tissue must overcome to deliver tidal volume; higher driving pressure indicates stiffer lungs or less favorable compliance and is linked to higher risk of ventilator-related injury. So the key is the difference between the plateau pressure and the PEEP, not the raw pressures themselves.
