Main section of the “PowerApp” with the calculation tool for mechanical power and its relative components (elastic, resistive and PEEP component). The first section-tab “Start” allows to enter data easily available bedside from the ventilator; the output section firstly shows the calculated driving pressure (cmH2O), elastance (cmH2O/l) and inspiratory airway resistance (cmH2O/l/s), followed by mechanical power (J/min), energy per breath (J) and its relative components (%). The next section-tab “Comparison” initially displays the current results and allows the clinician to predict the variations in mechanical power, energy and its components by changing the ventilator setting or the physiological conditions
