Catheter-free pH Monitoring (Bravo®) is a catheter-free test for gastroesophageal reflux disease (GERD). Previous methods of diagnosis and management of GERD involved the use of intrusive and less accurate catheters.
The Bravo® catheter-free experience allows for more precise and extensive data, and it provides a much more comfort able experience.
A small pH capsule is temporarily attached to the wall of your esophagus during an upper endoscopy. Over the next 48-96 hours, data will be collected and sent to a small, cell phone-sized receiver that you wear on your belt or waistband.
Upon completion of the Catheter-free pH Monitoring (Bravo®) test, your natural digestive processes will propel the capsule through your digestive tract.
You should look into Catheter-free pH Monitoring (Bravo®) to:
Your doctor will give you instructions to prepare for the Catheter-free pH Monitoring (Bravo®) procedure. Most likely, you will be asked to fast for at least 4-8 hours before the upper endoscopy.
Inform your doctor of:
You’ll need to plan for a ride home from the office as it is not advised for patients to drive for the remainder of the day due to effects from the medication. It’s important to follow all of your doctor’s instructions.
The placement process involves an upper endoscopy. During the upper endoscopy you’ll be asked to lay on your back or on your side.
You may be given:
Your doctor will ask you to swallow as the endoscope is worked down your esophagus.
You won’t be able to speak while the endoscopy is in progress, but you will be able to breath and make noises.
You might feel:
Once the pH capsule has been placed in your esophagus, you’ll be sent home with your ride.
During the study you may eat normally and continue your normal routine. You can take a bath and sleep without wearing the receiver, but you must stay within 3 feet of the receiver at all times.
You may notice a slight feeling of something “stuck” in the back of your throat. Don’t be alarmed by it, it’s just the capsule. Chewing food carefully and drinking liquids may minimize this sensation. You’ll be given a diary to record certain instances.
You’ll be asked to record any times that you:
For more information about the placement of the capsule, visit the Upper Endoscopy page.
You’ll be asked to return in 48-96 hours so we can retrieve your diary and the receiver. The data will be uploaded into a computer and your doctor will analyze it to determine a diagnosis.
A few days after the study, the capsule will fall from the lining of your esophagus and pass through your digestive system. You do not need to retrieve the capsule. It can be flushed away after passing through your body.
Do not have an MRI study for 30 days after undergoing Bravo® pH monitoring.
