The BRAVO pH capsule measures and monitors gastroesophageal acid levels (pH). This is done to evaluate gastroesophageal reflux during a normal day. The BRAVO capsule is placed into the esophagus above the lower esophageal sphincter (LES). After the capsule is positioned, it is applied by suction to the esophageal wall. This will secure the capsule into place.

BRAVO Procedure Preparation 

  • No food or liquids (this includes water) minimally 6 hours prior to the procedure.
  • You may also have diet and/or medication restrictions the week prior to the exam. Please refer to your physician for detailed instructions. 
  • Plan to take the day off from work for the exam.
  • Plan to have someone you know drive you home. Since the procedure is usually performed with intravenous sedation, you will be instructed to not drive a car or return to work until the next day.
  • Contact the physician and inform him or her of any special needs, medical conditions, latex allergy or current medications you are taking.
  • The GI Lab staff will attempt to contact you the evening before your procedure to answer any questions you may have.
