Clinical application of a ventilation strategy based on the P-V curve in obese patients undergoing gynaecological laparoscopic surgery

PCV-VG, based on the pressure-volume curve, significantly reduced intraoperative peak airway pressure, was associated with smoother haemodynamic, and regulated intraoperative pneumoperitoneal pressure and position in obese patients undergoing gynaecological laparoscopic surgery. The ventilation method also significantly improved the patients' postoperative comfort.
