Figure.. Forced Inspiratory Suction and Swallow Tool
The tool has a mouthpiece on the top, a body in the middle, and an adjustable cap with a pressure value on the lower end. The valve and the body's dimensions are designed to generate approximately −100 cm H2O in adults and −50 cm H2O in children. Directions: Get a cup half-filled with water and submerge the lower end under water. Forcefully suction through the mouthpiece and subsequently swallow the water; expect some resistance when you suction the water. The hiccups are usually expected to stop instantly in 1 to 2 attempts.
