Andersen Nasogastric Tube®: If it's bubbling,
The Andersen Tube is a vented
(bilumenal) gastric tube designed to keep the stomach continuously and
completely empty. It has 24 aspirating ports in the tip of the tube
that are designed to screen out particulate matter too large to pass through
the tube. It is made of exceptionally soft and pliable vinyl for patient
All tubes are FDA-approved and sterilized.
The air vent in all Andersen Nasogastric Tubes is now equipped with a
unique non-wettable filter that acts to prevent vent-tube reflux.
The configuration of Andersen Nasogastric Tubes maintains the vacuum
in the aspirating tube within a range (to -24 inches H20) that will
not damage delicate gastric mucosa. Because the vent tube is attached
to the outside of the aspirating tube, and not recessed in it, the
inside of the aspirating tube is perfectly round and can pass a
greater volume of aspirant than other tubes of the same French size.
24 Aspiration Ports
Andersen Nasogastric Tubes are less likely to block than other gastric
tubes because their aspirating ports are perfectly round and have
a smaller diameter than the cross section of the aspirating lumen.
Thus particles too large to pass through the aspirating ports cannot
pass into the aspirating tube. Moreover, the aspirating ports are
polished to remove any burs that might trap mucous or particulate
Ease of Placement
Andersen Nasogastric Tubes have marks at 40, 50, 60, and 70cm from the most
proximal from the aspiration port. These marks encourage correct placement,
in the average adult, of the aspirating tip of the tube in the cardia
of the stomach. Pediatric models of Andersen Nasogastric Tubes have multiple
markings to facilitate placement in children.
Andersen Nasogastric Tubes are extruded from a particularly soft, medical
grade vinyl and their distal end is molded into a gently rounded tip to
assure atraumatic passage and extended patient tolerance.
A glance from across the room will assure you that the Andersen Nasogastric
Tube is functioning properly. The need for routine irrigation, and routine
checks for tube patency or pump function are eliminated because — If
It’s Bubbling, It’s Working!
