Enteral Pump

Definition

Mechanical device that delivers enteral nutrition at a controlled, consistent rate via feeding tube. Ensures precise volume delivery and allows for continuous, nocturnal, or cyclical feeding regimens.

How it works

Enteral pumps are essential equipment for safe, controlled delivery of tube feeding, particularly in critical care settings and jejunal feeding. They deliver formula at programmed rates independent of patient position or gravity, ensuring consistent nutrient delivery and reducing variation. Pumps are especially valuable for managing high-osmolarity formulas, slow post-pyloric feeding, and nocturnal feeding regimens. Modern pumps include safety features such as occlusion detection, air-in-line detection, and alarms for pump malfunctions, reducing complications and increasing safety.

Role

Delivers enteral nutrition at controlled rates with safety mechanisms, allowing flexible feeding schedules while ensuring consistent nutritional support and minimizing complications.

Examples

• Gravity drip with flow control for gastric feeding
• Peristaltic pump for jejunal feeding
• Nocturnal feeding pump (10-hour cycle)
• Portable pump for ambulatory patients

Recommendations

Use pumps for jejunal feeding and high-osmolarity formulas. Set alarms and check tube patency regularly. Ensure pump is functioning properly before each shift. Train patients and caregivers on safe pump operation if used at home.

Key takeaway

Enteral pumps provide safe, precise nutritional delivery with reduced complications compared to gravity feeding, particularly for challenging feeding routes.
