Description

<p>We aimed to clarify mask fit pressure and air leakage factors during mask ventilation using the EC clamp method. The method showed high mandibular coverage but low nasal coverage. We found a positive correlation between maximum ventilation and coverage of the cheek, mouth corner, and upper mouth corner on the opposite side from which the mask was held. A strong correlation also existed between maximum ventilation and the cheeks on the opposite side. The results imply the importance of firmly holding the cheek and mouth corners on the opposite side of mask retention to obtain adequate ventilation.</p>
