Bravo pH Monitoring Procedure

The Bravo pH Monitoring System for GERD is simple and convenient. It usually takes a few minutes to place the pH capsule, and you can maintain your normal activities during the 24- to 48-hour test.

Before the Test

The capsule can be placed quickly, so there’s no need for a hospital stay. Many people go to work or school during the test period. Instructions vary among doctors. Your doctor will give you full instructions before the test.

Placing the pH Capsule

You will sit or lie back while your doctor inserts the pH capsule into the esophagus. After the capsule is in place, suction is applied, drawing a small amount of tissue into the capsule. The capsule is locked in place with typically little or no discomfort.

During the Test

As soon as the capsule is attached, it begins measuring the pH levels in your esophagus. The capsule transmits these measurements wirelessly to a small receiver you wear on your waistband or belt.

The receiver is about the size of a standard pager, and has three symptom buttons. Simply press the appropriate button during the study when you experience heartburn, regurgitation, or chest pain.

You will also be asked to record periods of eating and sleeping in a diary throughout the test. Your doctor will give you complete instructions at the time of your test.

After the Test

When the pH study is complete, return the receiver and diary to your doctor. The information stored in the receiver will be uploaded to a computer. Your doctor will analyze your results to determine if you have GERD and plan the best treatment for your heartburn symptoms.

The disposable capsule will spontaneously detach and pass through your digestive system a few days after the test period. Only a small area of esophageal tissue is affected by the capsule.
