In electromagnetic placement for NGT placement, is pH monitoring used to confirm placement?

• A. Yes, pH monitoring is used
• B. No, pH monitoring is not used in this placement
• C. Only for certain patients
• D. pH monitoring is standard in all cases

Answer: (B)

In electromagnetic placement, the tube’s tip location is determined in real time by the tracking device as the tube is advanced. Because the device provides the location, pH testing of aspirate isn’t used to confirm placement as part of this method. Traditional pH monitoring is a separate, bedside check used when relying on aspirate acidity to verify gastric position, not for confirming placement with an electromagnetic guidance system. Radiographic confirmation may still be required by institutional policy, but pH monitoring isn’t the method used to verify placement with this technique.
