Fig. 1From: Positive end-expiratory pressure setting based on transpulmonary pressure during robot-assisted laparoscopic prostatectomy: an observational intervention studyEffects of increasing PEEP on driving pressure (A), transpulmonary driving pressure (B), respiratory system compliance (C), and lung compliance (D) during robot assisted laparoscopic prostatectomy. PtpEEP0 PEEP levels corresponding to the end-expiratory transpulmonary pressure levels of ≥0 cmH2O were achieved. *P < 0.05, ⁑P < 0.01Back to article page
