Covidien's Salem Sump™ nasogastric tubes enjoy world wide name brand recognition. The dual lumen tube allows for safer continuous and intermittent gastric suctioning. The large lumen allows for easy suction of gastric contents, decompression, irrigation and medication delivery. The smaller vent lumen allows for atmospheric air to be drawn into the tube and equalizes the vacuum pressure in the stomach once the contents have been emptied. This prevents the suction eyelets from adhering to and damaging the stomach lining.
