Bravo 48 hour pH Monitor

What Is the Bravo pH Monitoring System?

Bravo pH capsule attached to delivery system The catheter-free test measures pH levels in your esophagus. These measurements allow your doctor to evaluate your heartburn and acid reflux symptoms and plan the best treatment for your diagnosis.

Your doctor will temporarily attach the capsule to the wall of your esophagus. The capsule is very small – about the size of a gel cap – and usually takes a few minutes to place.

Once the capsule is in position, suction is applied, and a small amount of esophageal tissue is drawn into the capsule, locking it in place.

The capsule takes Bravo Receiver continuous pH measurements for up to 48 hours and transmits that information wirelessly to a small receiver you wear on your waistband. After the study, information from the receiver is uploaded to a computer for analysis.

You can eat normally and engage in your usual activities during the test. The disposable pH capsule will spontaneously detach and pass through your digestive system after several days.

Benefits

The world’s first catheter-free pH test, Bravo provides a more tolerable and convenient way to evaluate your heartburn symptoms when compared to catheter-based pH monitoring systems.1

The capsule is temporarily attached to the wall of your esophagus. The capsule transmits pH information wirelessly to a small receiver worn on your belt or waistband. Data can be transmitted approximately 3 feet, which means you can take the receiver off to shower and sleep without interrupting the test.

Most importantly, a catheter-free test allows you to engage in your usual activities during the test period:

  • Eat normally
  • Bathe and sleep comfortably
  • Maintain your daily life

The Bravo System allows you to perform your normal activities during the pH test, which has the potential to provide a more accurate picture of your acid exposure compared to data collected using catheter-based systems.2

Risks

The Bravo pH test is not for everyone. If you have bleeding diathesis, strictures, severe esophagitis, varices, obstructions, a pacemaker, or an implantable cardiac defibrillator, you should not undergo a Bravo pH test. Additionally, because the capsule contains a small magnet, you should not have an MRI study within 30 days of undergoing the Bravo pH test.

Potential complications associated with gastrointestinal endoscopy include perforation, hemorrhage, aspiration, fever, infection, hypertension, respiratory arrest, and cardiac arrhythmia or arrest.

Potential complications for using the Bravo pH Monitoring System include the following events:

  • Premature detachment of the pH capsule
  • Failure of the pH capsule to detach from the esophagus within several days after placement, or discomfort associated with the pH capsule, requiring endoscopic removal
  • Tears in the mucosal and submucosal layers of the esophagus, causing bleeding and requiring possible medical intervention
  • Perforation

Potential complications associated with nasal intubation include: sore throat, discomfort, and nasopharyngeal damage resulting in bleeding and soft tissue damage.

All pH testing procedures carry some risks. Talk to your doctor about your concerns and testing options.

Bravo pH Monitoring Procedure, Before, During & After Test.

Bravo

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.

Frequently Asked Questions

Q: What is pH testing?

A: A pH test measures the degree of acidity or alkalinity in your esophagus. The test period usually lasts 24 to 48hours, and measures acidity in two ways:

  • How often stomach acid flows into the lower esophagus
  • Degree of acidity during the test period

Information from the pH test helps your doctor diagnose GERD and plan your treatment.

Q: What is the Bravo pH Monitoring System?

A: Bravo is the world’s first catheter-free pH monitoring system. With the Bravo system, a miniature pH capsule, approximately the size of a gel cap, is temporarily attached to the wall of your esophagus. The capsule transmits pH information wirelessly to a portable receiver you wear on your waistband.

The capsule usually takes a few minutes to place. There’s no uncomfortable catheter during the test period, which means you can eat, sleep, shower, and engage in all your normal activities.

Q: Why should I choose the Bravo system over a catheter-based test?

A: When it comes to evaluating your heartburn symptoms, the Bravo system provides a safe, well-established alternative to catheter-based pH monitoring.

A study showed that the Bravo system is significantly better tolerated than catheter-based tests:

  • Less nose and throat pain
  • Fewer reports of runny nose

What’s more, study participants said the Bravo system interfered less with their daily activities – including sleep – and had a higher overall satisfaction rate and better quality of life than those using the catheter-based test. However, some patients with the Bravo system complained of more chest pain and discomfort than patients with the traditional pH probe.

The Bravo system allows you to perform your normal activities during the pH test, which has the potential to provide a more accurate picture of your acid exposure.

Q: Who is not a candidate for the Bravo pH Monitoring System?

A: The Bravo system is not for everyone. If you have bleeding diathesis, strictures, severe esophagitis, varices, obstructions, a pacemaker, or an implantable cardiac defibrillator, you should not have a Bravo pH test.

Additionally, because the capsule contains a small magnet, you should not undergo an MRI study within 30 days of having a Bravo pH test.

Talk to your doctor about your symptoms and testing options to see if a Bravo pH test for GERD is right for you.

The Bravo system is available by prescription only.

Potential complications associated with gastrointestinal endoscopy include perforation, hemorrhage, aspiration, fever, infection, hypertension, respiratory arrest, and cardiac arrhythmia or arrest.

Potential complications for using the Bravo pH Monitoring System include the following events:

  • Premature detachment of the pH capsule
  • Failure of the pH capsule to detach from the esophagus within several days after placement, or discomfort associated with the pH capsule, requiring endoscopic removal
  • Tears in the mucosal and submucosal layers of the esophagus, causing bleeding and requiring possible medical intervention
  • Perforation

Potential complications associated with nasal intubation include: sore throat, discomfort, and nasopharyngeal damage resulting in bleeding and soft tissue damage.
