Bravo pH Study

This procedure can be performed with or without an upper endoscopy.

With Upper Endoscopy:

Why am I having this study?

Your doctor has ordered a test for your esophagus called a Bravo pH study and is done along with your upper endoscopy.  It shows the doctor the amount of stomach acid that causes your heartburn during a normal day.

What can I expect?

The procedure will be performed while you lie on a stretcher. The nurse will monitor your blood pressure, pulse, and temperature. You will be given an IV and relaxing medications.  As the gastroscope is carefully advanced, the doctor will look at your esophagus and place the tiny Bravo capsule. This capsule gives data to a pager worn for 48 hours.

What should I do to prepare?

The nurse will ask you questions about what medications you are taking and your medical history. Please do not have anything to eat or drink 6 hours prior to the test. If you are on heart or blood pressure medications you will need to check with your physician and let him decide if you should take these the morning of the exam.

Discharge and follow-up

You will be taken to the recovery room and may feel drowsy and sleep for a short time. You may feel some bloating from the air put in during the procedure. Your entire procedure will last for approximately 2 hours. You will be given written instructions to follow when you get home. A diary sheet will be given to you to record what you eat, when you sleep, and when you have heartburn. You will need to return the pager after 48 hours so that the results of the test can be sent to the doctor. It takes about 2 weeks for your doctor to receive results of your test.

Without Upper Endoscopy:

Why am I having this study?

Your doctor has ordered a test called a BRAVO pH Study. It shows the doctor the amount of stomach acid that refluxes up into your esophagus during a normal day.

What can I expect?

The procedure will be performed while you sit in a recliner. The nurse will monitor your blood pressure, pulse, and temperature prior to the test. You will have your throat sprayed with a numbing solution called Cetacaine. During this test, a capsule is passed through your mouth and suctioned to the wall of your esophagus. This capsule transmits data every 12 seconds to a pager that is worn for 48 hours. This capsule naturally sloughs or falls off in 5-7 days, travels through your system and is not retrieved.

IMPORTANT: This pager needs to be returned to the hospital in 48 hours to allow us retrieve or download the information.

What should I do to prepare?

The nurse will ask you questions about what medications you are taking and your medical history. Please do not have anything to eat or drink 6 hours prior to the test. If you are on heart, blood pressure, or stomach (PPI’s) medications you will need to check with your physician and let him decide if you should take these the morning of the exam.

Discharge and follow-up

After the procedure your blood pressure, pulse, and temperature will be taken. You will be in the department for approximately 1-2 hours, if you have an EGD by a physician. If this is inserted by the nurses, you will not be sedated and you can drive home. You will be in the department about 45 minutes. This is not a long procedure. You will be given written instructions to follow when you get home. A diary sheet will be given to you to record what you eat, when you sleep, and when you have heartburn.

It takes about 2 weeks for your doctor to receive results of your test.
