The BRAVO capsule measures pH levels in the esophagus. The capsule will send the pH levels via signals to a BRAVO receiver during the study. The receiver is about the size of a cell phone and can be attached to your waistband or belt. You will need to keep the receiver within 3 feet at all times for the capsule signals to be sent to the receiver. You can shower or bathe, but make sure the receiver is within 3 feet of the capsule without getting wet.
The receiver has buttons that you will push during the study. You will also be given a diary. You will keep track of symptoms, when you eat, body position (lying down, sitting or standing) and peak flow measures using the buttons on the receiver and the diary. The nurse will show you how to use the BRAVO receiver and diary.
It is important that you maintain all regular activities as much as possible during the study in order to obtain an accurate assessment of reflux through a for 48- 96 hours. This includes maintaining typical meals, activities, exercise, sleep, etc., while the BRAVO capsule and receiver are in place. If you have any questions, please ask.
