Impact of PEEP during laparoscopic surgery on early postoperative ventilation distribution visualized by electrical impedance tomography.

Abstract

Changes of postoperative ventilation can be imaged by EIT. Intraoperative PEEP ventilation has a positive effect on early postoperative ventilation distribution, even though not all PEEP patients benefit from mechanical PEEP ventilation the same way. Intraoperative PEEP results in a more homogeneous ventilation distribution by trend.
