From the evaluation of external anatomic landmarks to the performance of nerve blocks for fiberoptic intubation an understanding of the anatomy of the airway will result in fewer attempts at intubation and improved success with fewer iatrogenic misadventures.

In all anesthesia cases the patient is first manually ventilated with a face mask until intubated or a laryngeal mask is introduced to obtain sufficient oxygen saturation of the blood during the application of instruments.

Differs from traditional intubation in that it uses weight-based doses of short-acting medications rather than gradually titrating the dose in order to forego bag-valve-mask ventilation and achieve more rapid intubation.
