Cohort respiratory data plotted against positive end-expiratory pressure (PEEP) level. The top panel shows the distribution of patient-specific elastance (E
) across the 10 patients at each PEEP level. The middle panel shows peak inspiratory pressure (PIP) and the bottom plot dynamic functional residual capacity (dFRC). Red cross outliers: the outliers in E
are mainly from patient 5. PEEP levels were classified by rounding to the nearest 5 cmH2O.
