Your doctor will place a capsule on the wall of the esophagus.
The Bravo pH Capsule (Medtronics, Minneapolis, MN) measures pH levels in the esophagus and transmits continuous esophageal pH readings to a receiver worn on the patient’s belt or waistband.
Symptoms that the patient experiences are recorded in a diary and/or by pressing buttons on the receiver unit.
Generally, 48 hours of pH data are measured with this probe.
The capsule eventually detaches and passes through the digestive tract in 5 to 7 days.
Esophageal manometry measures muscle contractions in your esophagus. The doctor may order this procedure if you’re thinking about anti-reflux surgery.
EMS is performed using electronic, pressure-sensitive transducers located within the catheter, or water-perfused catheters with lateral side holes attached to transducers outside the body.
Traditionally, the water perfused catheter has largely been replaced by high resolution motility (HRM).
