Catheters, Esophageal, Manometric
Definition : Esophageal catheters designed to measure the pressure in the esophagus. These catheters usually consist of ruled tubes with several recording ports or pressure transducers; the catheter is introduced, either through the mouth or the nose, and advanced until its distal tip is about five cm from the lower esophageal sphincter. Some of these catheters include a sensor for recording pH in the lower esophagus. Manometric esophageal catheters are attached to a recorder that generates a graphic showing the pressures from the upper and lower esophageal sphincters and from several points (e.g. four) along the esophagus.
