Effects of positive end-expiratory pressure and oxygen concentration on non-hypoxemic apnea time during face mask ventilation of anesthesia induction: A randomized controlled trial

Effects of positive end-expiratory pressure and oxygen concentration on non-hypoxemic apnea time during face mask ventilation of anesthesia induction: A randomized controlled trial

Background: The optimal ventilatory strategy for the face mask ventilation during anesthesia induction is still unknow.Methods: We evaluated the effect of two positive end-expiratory pressure (PEEP) levels (0 cmH2O and 6 cmH2O) and two oxygen concentration levels (1.0 and .6) on non-hypoxemic apnea...
