Quick Answer
A Salem Sump stomach tube is a large-bore, dual-lumen nasogastric tube used primarily for gastric decompression and drainage. The larger lumen provides a pathway for removing gastric fluid and air, while the smaller air-vent lumen allows atmospheric air to enter the system during suction. The terms Salem Sump stomach tube, Salem Sump nasogastric tube, and Salem Sump NGT generally refer to the same type of dual-lumen gastric drainage tube.
What Is a Salem Sump Stomach Tube?
A Salem Sump tube is inserted through the nose and advanced into the stomach, so it is a type of nasogastric tube. It may also be described as a Salem Sump stomach tube, gastric sump tube, dual-lumen NG tube, or Salem Sump NGT.
Its defining feature is the dual-lumen construction. One lumen is used for gastric drainage or suction, while the second lumen functions as an air vent. This design distinguishes the Salem Sump tube from many single-lumen gastric or feeding tubes.

How Do the Two Lumens Work?
Main Suction Lumen
The larger lumen is the main pathway for gastric drainage. It may be connected to the prescribed drainage or suction system to remove gastric fluid, swallowed air, and other stomach contents.
Air-Vent Lumen
The smaller lumen, often identified by a blue pigtail or vent port, allows atmospheric air to enter the tube system while suction is applied through the main lumen. This helps the tube maintain its sump function and limits excessive negative pressure at the distal openings.
The vent lumen is not a second suction channel and should not be treated as a general-purpose feeding, medication, or irrigation port unless the instructions for the specific product state otherwise.
| Tube Component | Primary Function | Key Point |
|---|---|---|
| Main lumen | Gastric drainage and suction | Connects to the prescribed drainage or suction system |
| Air-vent lumen | Allows atmospheric airflow during suction | Often identified by a blue pigtail or vent port |
| Distal openings | Provide access for gastric drainage | Configuration depends on the specific product design |
Why Does the Air Vent Matter During Gastric Suction?
When suction is applied through a single-lumen gastric tube, the stomach wall may be drawn toward the distal openings as the stomach collapses. The air-vent lumen allows air into the tube system, helping maintain sump action and reducing direct suction against the gastric mucosa.
This vented design is the main structural difference between a Salem Sump tube and many standard single-lumen gastric tubes.

Is a Salem Sump Tube an NG Tube?
Yes. A Salem Sump tube is an NG tube because it is passed through the nose into the stomach. However, not all NG tubes are Salem Sump tubes.
“NG tube” is a broad category that includes tubes intended for feeding, medication delivery, drainage, or decompression. A Salem Sump is a specific large-bore, dual-lumen NG tube associated primarily with gastric drainage and decompression.

Common Clinical Contexts
Salem Sump tubes are commonly associated with temporary gastric drainage or decompression in situations such as:
Postoperative gastric decompression.
Removal of accumulated gastric fluid or swallowed air.
Management of gastric distension.
Bowel obstruction management as directed by the clinical team.
Gastric drainage before or after selected procedures.
Tube selection, placement, suction settings, and ongoing management should follow the healthcare facility’s protocol and the instructions for the specific device.
Can a Salem Sump Tube Be Used for Feeding or Medication?
Some large-bore NG tubes may permit fluids or medications to be introduced through the main lumen when clinically prescribed. However, a Salem Sump tube is primarily selected for gastric decompression rather than routine or long-term enteral feeding.
Feeding capability, medication administration, and connector compatibility depend on the specific tube design, connector configuration, and manufacturer’s instructions for use. The air-vent lumen should not be used as a feeding or medication port.
What Should Buyers Confirm Before Ordering?
When evaluating a Salem Sump tube or dual-lumen stomach tube, buyers should confirm the specifications of the actual product rather than relying only on the general product name.
| Procurement Item | What to Confirm |
|---|---|
| Size and length | Available French sizes and tube lengths |
| Tube construction | Material, flexibility, distal openings, and tip design |
| Placement references | Graduation markings and radiopaque line, where applicable |
| Connector design | Main suction connector, vent configuration, and optional connector versions |
| Packaging and documentation | Sterile status, packaging format, shelf life, labeling, and regulatory documents |
| Supply requirements | Standard product, OEM, private-label, and packaging requirements |

Frequently Asked Questions
Is a Salem Sump tube the same as a nasogastric tube?
A Salem Sump is a specific type of nasogastric tube. It has two lumens and is primarily designed for gastric drainage and decompression.
What is the blue port on a Salem Sump tube?
The blue port or pigtail is the air-vent lumen. It allows atmospheric air to enter the tube system while suction is applied through the main lumen.
Which lumen is connected to suction?
The larger main lumen is connected to the prescribed drainage or suction system. The smaller vent lumen performs the air-vent function.
Is a Salem Sump tube mainly a feeding tube?
No. It is primarily a gastric drainage and decompression tube. Any feeding or medication use depends on the specific product configuration, clinical protocol, and instructions for use.
Conclusion
A Salem Sump stomach tube is a dual-lumen nasogastric tube designed primarily for gastric drainage and decompression. Its larger lumen removes gastric contents, while the smaller air-vent lumen supports airflow during suction. Understanding this two-lumen structure helps distinguish the Salem Sump tube from feeding-specific and other single-lumen NG tubes.
For purchasing decisions, buyers should verify the actual tube size, material, connector configuration, markings, packaging, and documentation supplied with the product.
