Can Individuals Control Pressure in Their Esophagus.

A catheter inserted through the nares, post appropriate anesthetization. The subject is then given 8 - 10 sips of water or semi viscous fluid during the routine study. At the conclusion of the clinical portion of the examination the manometer catheter is typically removed by the technician at that point. For the purposes of this research study the catheter will remain in place to examine pressures specifically at the lower end of the esophagus during various breathing patterns and training activities to see if pressures can be increased with instruction.
