In this episode, we explore the evidence on whether lower intraoperative tidal volumes (e.g., 6 vs. 9 cc/kg) reduce postoperative pulmonary complications.

Our guest is Dr. Avery Tung. Dr. Tung is Professor of Anesthesia & Critical Care at the University of Chicago and Section Editor for Critical Care & Resuscitation for Anesthesia & Analgesia.
