Inspiratory drive. The mean inspiratory drive, measured by the inspiratory change in electric activity of the diaphragm (ΔEdi), is shown in relation to the PEEP level. Additionally, the median levels of PaO2 and PaCO2 in relation to the PEEP level are displayed. A ΔEdi increase was seen during the high PEEP levels even though a distinct PaO2 increase was observed. PaCO2 levels did not change statistically significant with the PEEP level. The black dots represent the ΔEdi of the incremental PEEP levels (0 to 15 cmH2O), and the circles represent the ΔEdi of the decremental PEEP levels (12 to 0 cmH2O). Gray boxes represent incremental and decremental levels of PaO2 and white boxes represents incremental and decremental levels of PaCO2. Outliers are not shown
