Bravo pH Monitor test is an endoscopically placed monitor that measures the pH (acid level) in the esophagus to determine if a patient has acid reflux, atypical symptoms of acid reflux, or how well the acid-suppressing medication is managing the condition.

The Bravo Capsule is used in the diagnosis, initial treatment, and management of chronic Reflux.

Your Physician will let you know if you should continue your antacid medications during the test or stop it. Please follow your daily routine, including eating normal meals, but avoid frequent snacking, chewing gum or sucking candies. Keep the Bravo receiver at arm’s length at all times, but avoid getting it wet. Make sure to press the appropriate buttons every time a symptom occurs, when you either eat or lay down. Please remember to return the receiver and your diary at the end of the study.

What to Expect

You will undergo an upper endoscopy while under sedation. During the procedure, if there is significant inflammation or damage in the esophagus, the physician will not proceed with capsule placement. However, if the lining of the esophagus appears normal, a catheter will be inserted into your esophagus, and the pH capsule will be temporarily attached to the lining of the esophagus. This capsule measures the pH level in the esophagus and transmits the date wirelessly to a portable receiver that you keep near you. The test period lasts about 48 hours. The capsule is small therefore you may eat normally and go about your daily routine. You will be given a diary to write down the times when you have reflux systems (for example, coughing, heartburn, regurgitation), either while eating or when lying down. After the test is completed, you return the diary and the Bravo Receiver to your Physician. The data is then uploaded to a computer, and analyzed by your Physician to diagnose your condition.
