Every airway maneuver will cause some degree of neck movement. Ventilation via face-mask technique requires lifting the mandible (jaw thrust) to the facemask. A significant degree of cervical spine motion induced by bag-mask ventilation has been reported on human cadavers with destabilized cervical vertebrae. However, to our knowledge, no quantitative data have reported evaluating the effects of bag-mask ventilation on cervical spine motion in living humans. We measured the cervical spine movement during bag-mask ventilation. ⋯ The lifting the mandible causes both extension and anterior disposition in the cervical vertebrae.
