Mechanical ventilation in the operating room frequently includes application of positive end expiratory pressure (PEEP). This is done to improve intraoperative oxygen delivery, as well as to improve lung mechanics postoperatively. PEEP increases intrathoracic pressure, decreasing venous return, and potentially raising venous pressure. This raises potential concern that PEEP may increase bleeding, particularly in operations […]
Does use of PEEP affect bleeding during functional endoscopic sinus surgery?
