Bravo pH Monitor

What is the Bravo® pH monitor?

The Bravo® pH monitor is a capsule-based, catheter-free alternative diagnostic procedure used to measure pH to effectively diagnose gastroesophageal reflux disease (GERD), also known as acid reflux disease.

GERD occurs when the muscle at the end of your esophagus doesn’t fully close or it opens too frequently, causing stomach acid to travel into the esophagus.


A GERD diagnosis can be confirmed with the Bravo® pH monitoring system by evaluating symptoms such as:

  • Bloating
  • Heartburn
  • Hoarseness or chronic sore throat
  • Nausea or upset stomach after eating (indigestion)
  • Regurgitation of acid into the mouth or back of the throat

What to expect during the procedure

During the procedure, the physician attaches a small capsule to the wall of the esophagus. The capsule then transmits pH information to a tiny receiver worn on the patient’s person for a period of 48 hours.

When the 48 hours are over, the data are uploaded and analyzed. The capsule is left to naturally pass through the digestive tract and is excreted.
