Nasal Specific/Bilateral Nasal Specific (BNS) uses finger cots, affixed/tied to a blood pressure bulb (a sphygmomanometer) to deliver an even and effective controlled force of pressure. The patient breaths out through their nose, and the finger cot is inserted the nasal passages.
When the finger cot/balloon is slid into the nasal passageway with a flat tooth pick. The patient is asked to breath out through their nose, this allows access and proper placement of the balloon into the passageway. The nose is lightly compressed around the valve of the pressure bulb, so that no air can escape. The patient then takes a deep breath in and holds it. While the patient is holding their breath the practitioner quickly and gently inflates the finger cot/balloon with two to four quick hand pumps/squeezes of the pressure bulb. Squeezing the pressure bulb applies air into the finger cot/balloon. As this air pressure becomes greater it pushes on the walls of the nasal passageways, eventually it squeezes its way through to the back of the throat. The practitioner then quickly releases this pressure via the valve on the stem of the pressure bulb. This process takes a few seconds.
