Anesth Analg
September 2018
Background: Recruitment maneuver and positive end-expiratory pressure (PEEP) can be used to counteract intraoperative anesthesia-induced atelectasis. Variable ventilation can stabilize lung mechanics by avoiding the monotonic tidal volume and protect lung parenchyma as tidal recruitment is encompassed within the tidal volume variability.
Methods: Forty-nine (7 per group) male Wistar rats were anesthetized, paralyzed, and mechanically ventilated.
