"Low Pneumoperitoneum Pressure: defined as an intrabdominal pressure between 8-12 mmHg during the laparoscopic procedure.~High Pneumoperitoneum pressure: defined as an intrabdominal pressure of 15 mmHg or more during the laparoscopic procedure.~Note: surgeons will set the pneumoperitoneum at the lowest value they are comfortable with based on their surgical criteria"
