24 Hour PH Monitor Instructions

Printer Friendly Version

Arrive at check in time, checking in at the Surgical Procedure Area (SPA) which is on the 3rd floor of Sacred Heart Medical Center at RiverBend located at 3333 RiverBend Dr.  Springfield, Oregon 97477.  You will park in parking structure S.

To prepare for 24 hour pH, follow these instructions carefully:

Nothing to eat or drink 4 hours prior to check in, including water.

Acid reducing medication needs to be discontinued for the testing.  Stop taking Prilosec, Nexium, Aciphex, Protonix or Prevacid 7 days before the test. H2 Blockers (Tagamet, Zantec, Axid, Pepcid) should be stopped 3 days before the test.  Antacids should be stopped 24 hrs. before the test.

Twenty‑four hour pH monitoring is a test to determine the severity of gastroesophageal reflux disease (GERD).  This test shows us which symptoms could be from gastroesophageal reflux disease, or if you might benefit from a surgery to correct gastroesophageal reflux.

Most people choose not to work the day of pH monitoring.  Otherwise, normal activities can be undertaken.  You should strive to eat normally and take normal rest and sleep periods.  It is also helpful to wear a shirt or blouse, which unbuttons down the front so the nurse can conceal the catheter under your clothing easily

You will start out in the Surgical Procedure Area (SPA).  The nurse will place a thin soft, flexible catheter through one of your nostrils so that the tip sits in the middle of your esophagus.  The tip of this probe measures acidity (pH).

The catheter is thin and soft and soon you will become more comfortable with it.  It will be secured at your nose and the other end will be connected to an information‑gathering instrument that you wear around your waist.  This instrument is the size of a small radio.

Because we are interested in knowing whether certain symptoms are associated with acid in the esophagus, we will ask you to keep a written log.  In this log you will mark the time and duration of certain symptoms such as chest pain, heartburn, and cough.

After approximately 24 hours, you will return to the SPA unit and the nurse will remove the catheter.  The information gathered will run through a computer and conclusions can be drawn regarding the severity of gastroesophageal reflux disease and its association with certain symptoms.
