  • It is passed from the nose into the stomach for feed­ing and for suction of gastric contents.
  • The tip is blunt and rounded with a lead pellet inside it.
  • The lead pellet makes the tube heavy and straight at the tip and also makes it visible on x-ray.
  • There are a number of side small holes away from the tip for suction of gastroduodenal contents and for feeding.
  • There are three circular marks over the tube. The first mark is about 40 cm. from the tip and indicates that the gastroesophageal junction has been reached.
  • The next mark is at 50 cms and marked by 2 circular lines.
  • This indicates that the tube has reached the body of the stomach.
  • The third mark consists of 3 circular lines 60 cms from the end and indicates that the tube has reached the pylorus.
