Is a nasopharyngeal airway which is inserted into the nose using a rotational action.
An airway adjunct to enable airway oxygenation/ventilation
Sizing – tragus of the ear to incisors of teeth
The diameter tube should be sized against the patients own little finger distal phalanx. A safety pin is placed in the end of the tube to prevent it being inhaled.
The appropriate airway size can be determined by measuring from the tip of the patient’s nose to the tragus of the ear (i.e. soft airway = measure ‘soft to soft’). The diameter of the airway should not exceed that of the patient’s little finger.
Indications:
* Used to bypass obstructions in the mouth, nose, nasopharynx or base of the tongue.
* Are typically better tolerated (and less likely to trigger the gag reflex) in patients who are partly or fully conscious compared to oropharyngeal airways.
Nasopharyngeal airways should not be used in patients who may have sustained a skull base fracture, due to the small but life-threatening risk of the NPA entering the cranial vault.
Complications
* Epistaxis
* Nasal trauma and bleeding
* Brain herniation in basal skull fractures
* Detoriation requiring intubation
