The Four Step Upper Airway Examination is used to assess several factors that may affect decisions concerning the patient’s airway management. This examination can usually be completed in less than a minute in the elective, awake, and cooperative patient. Modifications of the examination will be dictated by the patient’s condition (e.g., unconscious patient, C-spine collar).

Clinical Pearl:

Difficulty with bag-mask ventilation is not always associated with difficulties in placement of an extraglottic device (e.g., LMA™) or ETT. If difficulties with BMV occur, simple maneuvers, such as placement of an oropharyngeal airway, nasopharyngeal airway, or jaw thrust, may solve the problem. If difficulties persist, consider immediate placement of an extraglottic device or ETT.
