Bravo™ pH Monitoring System

The Bravo™ pH Monitoring System measures pH to test for gastroesophageal reflux disease in older children. The device is attached to the esophagus during an endoscopy— examination of the inside of the body using a lighted, flexible instrument.

  • The Bravo™ pH capsule, about the size of a gel cap, is temporarily attached to the wall of the esophagus.
  • The capsule then measures pH levels (acid levels) for up to 48 hours in the esophagus and transmits readings by radio telemetry to a receiver worn on the patient’s belt or waistband.
  • The patient also presses buttons on the receiver to keep a diary of symptoms.
  • After the study, data from the receiver is uploaded to a computer and diary information is entered for analysis to help make diagnosis and plan treatment. 
  • Normal patient activities such as swallowing, eating and drinking should cause the disposable pH capsule to detach and effortlessly pass through the digestive tract in about six days.
