Thus continue practice in 'air intake' and 'air expulsion' for a week.
For our information
｡?hile air is injected or inhaled into the lower pharynx and the upper esophagus, breathe in as little air as you can through the stoma.
° Some patients put their hand on their chest in order to lessen the awkwardness of movement during the intake and expulsion of air. Take in air, expel it, then hold your breath and take in air quickly.
｡?hile you are emitting air out of the esophagus, some say, you had better learn to hold your breath as much as possible. It is because if you breathe out air through the stoma while speaking, the volume of your thorax is diminished, and as a result, the pressure on your pharynx and esophagus decreases even if you apply a great strain to your abdomen.
