By blowing up a balloon using the nose, the child performs the Valsalva manoeuvre to increase pressure in the nasopharynx. During the deflation phase of the balloon, air is blown up the nose and the child can be encouraged to swallow, producing a Politzer manoeuvre.
The device is used two to three times daily. During each session, the child inflates the balloon once via each nostril.
The device is placed into one nostril and the other nostril is blocked. The device is activated (blowing air into the nose) and the patient swallows, producing a Politzer manoeuvre.
Treatment may be repeated twice in each nostril, twice daily, and continued until symptoms resolve.
