The pH monitoring, or esophageal acidity test, measures how often and for how long stomach acid enters the esophagus. It is helpful in evaluating gastroesophageal reflux disease (GERD) and the effects of medications currently used to treat GERD. Symptoms of GERD include recurring or chronic heartburn and may lead to more serious health issues.

Traditional 24 hour pH monitoring procedures involve inserting a catheter through the nasal passage into the stomach, then withdrawn back into your esophagus.  The catheter directly connects to a monitoring device that records acid levels in the esophagus. You will wear this monitor on a strap and will be asked to keep a diary of your symptoms and activity over the next 24 hours. The next day you will return and the tube will be removed. The information from the monitor will be compared to the diary you provide.

The Bravo system offers a new level of comfort and mobility during pH monitoring.

The Bravo system is a patented pH monitoring system that eliminates the catheter, causes less discomfort and allows greater freedom of movement than traditional pH monitoring procedures.  An EGD is normally done in conjunction with the Bravo.  A small capsule is attached to the side of the esophagus during the EGD.  Wireless signals are transmitted from the capsule to a monitor over the next 48 hours.  The monitor must be kept close to the body.  The monitor can be attached to a belt or strapped across the shoulder.  The monitor is to be returned to the Endoscopy Unit at the completion of your study for downloading into a computer.
