In the researchers' words
The steep trendelenburg position and pneumoperitoneum during laparoscopic surgery have the potential to cause an adverse effects on respiratory mechanics and gas exchange. Previous studies have proposed that a prolonged I:E ratio ventilation improved respiratory mechanics and gas exchange. Therefore, the aim of this study is to evaluate whether a prolonged I:E ratio ventilation improves gas exchange and respiratory mechanics in patients undergoing robot-assisted laparoscopic radical prostatectomy.
