When should you not use an NPA?

NASOPHARYNGEAL AIRWAY (NPA) The NPA is indicated when insertion of an OPA is technically difficult or dangerous. NPA placement can be facilitated by the use of a lubricant. Never force placement of the NPA as severe nosebleeds may occur. If it does not fit in one nare, try the other side.

What is the most common complication after inserting an oral airway?

Two major complications can occur with the use of OPAs: iatrogenic trauma and airway hyperreactivity. Minor trauma, including pinching of the lips and tongue, is common. Ulceration and necrosis of oropharyngeal structures from pressure and long-term contact (days) have been reported.
