In laparoscopic cholecystectomy method, Insufflation of CO2 in abdominal cavity causes positioning of the diaphragm upwards, a decrease in lung's volume and its compliance, an increase in the airway resistance, mismatch between the atelectasis and the ventilation perfusion. Although there are numerous studies in laparoscopic surgery, only a few of them investigate the effects of laparoscopic surgery on the cardiopulmonary and the respiratory mechanics. The investigator aimed To examine the effects of pressure-controlled and volume-controlled ventilation modes on cerebral oximetry and blood gases in laparoscopic cholecystectomy operations.
