  1. The value of each parameter before pneumoperitoneum was the average value measured 3 and 1 min before CO2 pneumoperitoneum. The value of each parameter after pneumoperitoneum was the average value measured 3 and 1 min after CO2 pneumoperitoneum and the delta value of each parameter was the difference between the average value measured 1 and 3 min after CO2 pneumoperitoneum and before CO2 pneumoperitoneum value
