Feeding Tube Types Comparison Chart
Two questions sort every feeding tube: how long will it be needed (nasal for weeks, surgical for months), and where must the formula land (stomach if it empties, jejunum if aspiration or gastric dysfunction says otherwise)?
Educational use only. Tube selection and placement are provider decisions; initial placement of blindly inserted tubes is confirmed by X-ray before any use. This material supports nursing education and exam review. It is not medical advice and is not a substitute for clinical judgment, institutional policy, or medical direction. Always follow facility protocols and current provider orders.
Tube-by-Tube Comparison
| Tube | Placement | Duration | Best For | Feeding Method | Key Nursing Considerations |
|---|---|---|---|---|---|
| Nasogastric (NG) — Levin | Nose → stomach; single lumen; bedside insertion, X-ray confirmation | Short-term (< 4–6 weeks) | Feeding and medications; intermittent suction if needed | Bolus, intermittent, or continuous | Verify before every use (length + pH); intermittent suction only — no vent lumen to protect mucosa |
| Nasogastric (NG) — Salem sump | Nose → stomach; double lumen with blue pigtail air vent; bedside insertion, X-ray confirmation | Short-term (< 4–6 weeks) | Gastric decompression/suction; can also feed | Decompression first; feeding when ordered | Pigtail stays open, above stomach level, never clamped or irrigated; tolerates continuous low suction |
| Nasoduodenal / Nasojejunal (small-bore, Dobhoff-type) | Nose → duodenum or jejunum, past the pylorus; stylet-guided, X-ray confirmation mandatory | Short-term (< 4–6 weeks) | High aspiration risk, gastroparesis, gastric outlet problems | Continuous by pump only — never bolus | Small lumen clogs easily — flush religiously; no residual checks (no gastric reservoir); the stylet is never reinserted while the tube is in the patient |
| PEG (percutaneous endoscopic gastrostomy) | Through the abdominal wall into the stomach; endoscopic/surgical placement | Long-term (> 4–6 weeks) | Chronic dysphagia (stroke, neuro disease), long-term nutrition with a working stomach | Bolus, intermittent, or continuous | Daily stoma care; check external bumper position per policy; site redness, leakage, or buried-bumper pain gets escalated; tube dislodged early after placement is urgent — the tract closes fast |
| PEJ / J-tube (jejunostomy) | Through the abdominal wall into the jejunum; endoscopic/surgical placement | Long-term (> 4–6 weeks) | Long-term feeding with high aspiration risk, gastric dysfunction, or post-gastric surgery | Continuous by pump only — never bolus | No reservoir below the tube — bolus feeding causes cramping and dumping-type intolerance; flush often; stoma care as for PEG |
Exam Traps
- ✦Anything ending in the jejunum is continuous-pump territory — bolus into a J-tube is always wrong.
- ✦Roughly 4–6 weeks is the dividing line: nasal tubes short-term, PEG/PEJ long-term.
- ✦X-ray confirms every blindly placed tube before first use; pH and external length are the ongoing bedside checks.
- ✦The Salem sump's blue pigtail is an air vent — never clamp, plug, or irrigate it.
- ✦A PEG that falls out in the first days after placement is urgent; the fresh tract closes within hours.
