2. Fig 1
Flow-volume loops observed during laparoscopic removal of gastric banding using a SLMA. Flow-volume loops show normal closure of the expiratory curve in a patient before carboperitoneum (a); early closure of the expiratory curve with air leaks during carboperitoneum (b); incomplete closure of the expiratory curve with minimal air leaks after increasing intracuff pressure of SLMA and reducing PIP during carboperitoneum (c). I, inspiratory curve; E, expiratory curve; PIP, peak inspiratory pressure; Vt exp, expiratory tidal volume; x, air leakage measured between zero and the point where the expiratory flow volume curve intersects the baseline.
