Esophageal pressures. (A–C) Esophageal plateau pressures (A), esophageal driving pressures (B), and end-expiratory esophageal pressures (C) after intubation (Baseline), with abdominal insufflation (Pneumoperitoneum), in Trendelenburg with pneumoperitoneum (Trendelenburg), and after release of abdominal insufflation with a level bed (Desufflation). The data are stratified by body mass index (kg/m2). The box plots show the medians and the 25th and 75 percentiles, whiskers are the 10th and 90th percentiles, and dots represent the outliers.
