Evidence has shown that driving pressure is the one parameter most relevant for lung-protective ventilation and strongly associated with hospital survival. However in all instances, we are talking about the amount of pressure set by the user to be applied above PEEP. This ensures that Hamilton Medical ventilators deliver reliable driving pressures across all modes.
In modes where the breath type may alternate (e.g., PSIMV+), the same parameter is referred to as Pinsp.
For mandatory breaths, it is called Pcontrol and for spontaneous breaths, it is called Psupport. There are three different labels for this delta pressure, which depend on the mode and breath type (and thus the different function). For the patient described above you would therefore set Pinsp at 5 cmH2O. Pinsp thus refers to the applied delta pressure and not the total inspiratory pressure including PEEP. However, on Hamilton Medical ventilators, the parameter Pinsp in NIV-ST is the same as Psupport in NIV.

On some ventilators, Pinsp refers to the total inspiratory pressure and equals PEEP plus the pressure support (Psupport), which is the additional (set) pressure applied for spontaneous breaths during the inspiratory phase. In the literature and amongst the different ventilator manufacturers, the labelling for certain parameters or values may vary.
