2. Fig 1
The box plots show the work of breathing (WOB, lower panel) and oxygen consumption as measured by the Deltatrac® device (V˙O2 measured, upper panel) during the different study conditions. The boxes represent medians (horizontal lines in each box) and quartiles. Five and 95% percentiles are indicated by the error bars. Single values outside of the percentile-ranges are drawn as dots. The circled ‘X’ sign indicates the statistically significant difference between the WOB measured during volume-controlled mechanical ventilation (control condition) and either of the two test-modes corresponding to SIMV+PS and BIPAP+PS.
