Explain why proper sizing of the nasopharyngeal airway is important.
What will be an ideal response?
Proper sizing for the patient is important. If the nasopharyngeal airway is too short, the airway would not separate the soft palate from the posterior wall of the pharynx. If the airway is too long, it would enter either the larynx and aggravate laryngeal reflexes or enter the space between the epiglottis and the vallecula leading to potential obstruction of the airway. The ideal length of the nasopharyngeal airway should have the distal end of the airway within 1 cm of the epiglottis.
