Bravo® pH monitoring is a wireless capsule-based test for evaluating acid reflux. Information is collected over 2-4 days to determine the frequency and duration of reflux events.
By using a miniature pH capsule attached to the oesophagus, pH data from the oesophagus can be wirelessly transmitted to a small recorder worn on a shoulder strap.
This procedure involves placement of the capsule during a planned gastroscopy.
