A range of instruments used to manage pathologies of the supralaryngeal tract (primary curve; top panel) and the laryngotracheal conduit (secondary curve; middle panel). The bottom image shows the set up for awake tracheal intubation using the Tritube. The manual jet ventilator showed in the middle panel should only be used in emergency situations (for trained experts only) and elective or semi-elective cases should be ventilated using a jet ventilator with in-built safety monitoring features like shown in Figure 8.
