Fig. 1

Airway (A – C) and transpulmonary (D – F) pressures during Volume- and Pressure-Controlled Ventilation. Boxplots with median, IQR and range; #: P < 0.01; *: P < 0.05. In A, the respective tidal volumes can be seen in the lower part of the diagram together with the corresponding plateau pressures. In B, the upper row depicts mean airway pressure and the lower row PEEP. Pplat, plateau pressure; VT kg^− 1BW, tidal volume per kilogram bodyweight; PEEP, positive endexpiratory pressure; ΔP_airway, airway driving pressure; Pinsp_transpulm, inspiratory transpulmonary pressure; Pexp_transpulm, expiratory transpulmonary pressure; ΔP_transpulm, transpulmonary driving pressure; BL, baseline; Hypo, hypovolaemia; Res I, resuscitation stage I; Res II, resuscitation stage II.
