Nasogastric Tubes



Confirming NG Placement

  • Instil air - use a syringe to inject air into the NG while auscultating over the epigastrium, listening for a gurgling sound. This should not be used as the sole method of checking placement.
  • Aspirate - aspirate stomach contents and check the pH (<5.5) using litmus paper.
  • Chest x-ray - ensure that the distal tip and side hole are below the diaphgram.
