About

Evaluation of effects of an endoscopic bite block on mask ventilation. In the present study, expiratory tidal volume and minute ventilation are measured under same pressure controlled mode in ventilator with three kinds of holding a mask. ( by one hand, one hand with an endoscopic bite block and two hand hold.)
