Frequently Asked Questions
Basic Operation
Q: How do I know if the pump is delivering accurately?
A: Monitor infusion progress against programmed parameters, check IV site regularly, and verify patient response. Report any concerns to biomedical engineering.
Q: What should I do if I make a programming error?
A: Stop the infusion immediately, assess patient safety, correct the programming error, and document the incident per hospital policy.
Q: Can I use any IV tubing with the infusion pump?
A: No, use only manufacturer-approved tubing sets designed for your specific pump model. Wrong tubing can cause accuracy problems and safety issues.
Q: How long can the pump run on battery power?
A: Typically 4-8 hours depending on flow rate and age of battery. Check battery indicator regularly and keep pump plugged in when possible.
Clinical Applications
Q: When should I use an infusion pump instead of gravity flow?
A: Use pumps for precise medication delivery, high-risk drugs, pediatric patients, critical medications, and when consistent flow rates are essential.
Q: Can I stop and restart an infusion safely?
A: Yes, but consider medication stability, line patency, and patient condition. Some medications require continuous delivery without interruption.
Q: How do I calculate infusion rates manually?
A: Use the formula: Flow rate (mL/hr) = Total volume (mL) ÷ Time (hours). Always double-check calculations and use pump calculations when available.
Troubleshooting
Q: The pump keeps alarming for occlusion, but the tubing looks clear. What should I do?
A: Check IV site for infiltration, verify all clamps are open, inspect for kinked tubing, and consider changing the IV site if needed.
Q: What do I do if the pump display goes blank?
A: Check power connections, try resetting the pump, and contact biomedical engineering if the problem persists. Have backup pump ready.
