Treatment of Snoring with a Nasopharyngeal Airway Tube
Soft polyvinyl chloride nasopharyngeal airway tube sizes and insertion results.
NPAT sizes (Fr)
Ability to be inserted
Hours tolerated during sleep
Outcomes from insertion and use during sleep
Tube kept hitting the inferior turbinate and could not pass.
Tolerated insertion for 2.5 hours and removed tube due to pain. Smartphone app: 0 snores. Bedpartner: 0/10 VAS.
Tolerated insertion for 0.75 hours and removed tube due to pain. Smartphone app: 0 snores. Bedpartner: 0/10 VAS.
Tolerated insertion 4.2 hours and snored during sleep. Smartphone app: 11.4 snores per hour. Bedpartner: 2/10 VAS.
Tube was easily inserted, however, was too short to stop simulated snoring, and therefore was not used overnight.
(Note: manufacturer is Teleflex; dimensions are also available at http://www.teleflex.com/.) Fr = French; NPAT = nasopharyngeal airway tube; NA = not applicable; and VAS = visual analog scale (0 = no snoring, 10 = snoring that could be heard through a closed door and significantly interrupted the bedpartner’s sleep).
