As with mask ventilation, intubation can be very easy or impossible. Laryngoscopic view are graded from grades I to IV: A grade I view exposes the entire laryngeal aperture and always affords an easy intubation. A grade II view allows exposure of just the posterior portion of the laryngeal aperture but usually affords a successful intubation. A grade III view exposes only the epiglottis A grade IV view exposes only the soft palate The success rate for tracheal intubation with a grade III or IV view is low. The usefulness of the preoperative airway evaluation is to identify those patients likely be a difficult intubation. Three easy tests have been developed to help evaluate the airway. The first test is called the Mallampati scale. This scale classifies the upper airway in terms of the size of
