Applying positive end-expiratory pressure to facemask ventilation improves post-induction lung atelectasis: a three-arm randomized controlled trial

Abstract Background Induction of general anesthesia is associated with rapid-onset lung atelectasis, which increases intrapulmonary shunt and potentially impairs oxygenation. We aimed to evaluate whether applying positive end-expiratory pressure (PEEP) to facemask ventilation during induction of gen...
