Bravo pH Study

The Bravo esophageal pH study is an outpatient procedure performed to measure the pH or amount of acid that comes up into the esophagus from the stomach during a 48-hour period. The test is used to help identify the cause of various symptoms, including: heartburn, gastroesophageal reflux disease (GERD), chest pain, asthma and chronic cough.

Looking at your esophagus
The physician will insert a flexible, lighted tube into your mouth and look at your esophagus, stomach and the first portion of your small bowel. Then the tiny Bravo capsule will be attached to the inside of your esophagus. The capsule will transmit how often and how much stomach acid is coming up into your esophagus, resulting in what is commonly called acid reflux.

You will be given sedation for this procedure so you must have someone to drive you home and record in your diary for the first four to six hours. During the remainder of your study you will need to press buttons and record in detail in a diary. The diary and recorder will need to be returned approximately 48 hours following the procedure. We will teach both of you in the pre-procedure area how to do the recording.

IMPORTANT:

  • Do not eat or drink anything after midnight before the procedure unless instructed by your physician.
  • You should be able to return to normal activities the day after your procedure.
