The external driving pressures were controlled sufficiently low, 20 60 kPa, on the order of capillary pressures.
External driving forces are addressed, including globalisation of customer industries, increasing cost pressures especially on commodities, strong pressure to increase shareholder value, new technological challenges and constraints to improve sustainability.
Under this assumption the only driving pressure at the forced oscillation frequency is the pressure applied at the mouth by the external generator.
The driving pressure was calculated by inspiratory pressure minus PEEP.
The variable parameters are the external driving temperatures.
Airway driving pressure was computed as airway pressure at end inspiration airway pressure at PEEP.
We defined "device driving pressure" as the peak mouth pressure minus the tele-expiratory mouth pressure.
PaO2/FiO2 improved during PEEPEIT and driving pressure decreased.
On the contrary, the lung stress, although related to airway driving pressure, could not be predicted by the driving pressure.
