The Levin tube is a single-lumen tube with holes near the tip.You connect the tube to a drainage bag or to an intermittent suction device to drain stomach secretions.The Salem sump tube has two lumina: one for removal of gastric contents and one to provide an air vent,which prevents suctioning of gastric mucosa into eyelets at the distal tip of the tube.A blue "pigtail" is the air vent that connects with the second lumen.Never clamp off the air vent,connect it to suction,or use it for irrigation.NG tube insertion does not require sterile technique.Clean technique is adequate.The Salem sump is preferred for gastric decompression.
