Yamasaki T, et al. – It has been reported previously that the nasal passage plays an important role in manual face mask ventilation. In this current study, researchers compared the change in pressure–controlled face mask tidal volume with and without nasal airway occlusion. Findings demonstrated that nasal passage obstruction considerably attenuated tidal volume achieved during face mask ventilation. As per observations, in some patients, it might be advantageous to relieve nasal airway obstruction for effective face mask ventilation
