ASA Difficult Airway Algorithm
The figure below summarises an algorithm developed by the American Society of Anesthesiologists for managing patients with a potentially difficult airway. The algorith emphasizes the importance of anticipating potential difficulties (e.g., difficult intubation, difficult ventilation, difficulty with patient cooperation, difficult tracheostomy ) as well as the relative merits and feasability of various basic airway management choices.
