Catheter Free Bravo 48 Hour pH Study
This procedure is usually done along with a Gastroscopy in which the patient is often sedated. A small capsule is clipped to the lower portion of the esophagus. This capsule measures the pH (acidity) of the esophagus and transmits this information to a small receiver, the approximate size of a beeper, worn by the patient. The study lasts for 48 hours. The patient will be instructed on a time and date to return the receiver to the Endoscopy Center for uploading of the data. The physician will be given a copy of the study for interpretation and will subsequently notify the patient of the results. Absolutely no MRI's can be performed for 30 days after the procedure.
Usually the patient is held without food or water for at least 6 hours prior to the procedure.
