Bravo® pH Probe
The Bravo® pH Monitoring System is a catheter-free way to measure pH from acid reflux disease. The Bravo system involves a pH capsule, about the size of a gel cap, that is temporarily attached to the wall of the esophagus. The Bravo™ pH Capsule measures pH levels in the esophagus and transmits readings via radio telemetry to the Bravo® Receiver worn on the patient’s belt or waistband. The patient also records symptoms he or she experiences in a diary by pressing buttons on the receiver. The Bravo® pH capsule collects pH measurements for up to 48 hours. After the study, data from the receiver is uploaded to a computer and diary information is entered for analysis to aid in the diagnosis and plan treatment. Normal patient activities such as swallowing, eating and drinking should cause the disposable pH capsule to detach and pass through the digestive tract in 5-7 days on average.
