What an infusion pump does and why safety matters at home
An infusion pump is a machine that delivers medicine or fluids into your body through a tube (called a catheter) placed in a vein, under your skin, or into your belly. Instead of getting medicine by hand from a nurse, the pump does it automatically on a schedule your doctor sets. At home, you become responsible for watching the pump, understanding its alarms, and knowing when something is wrong enough to call for help.
Home infusion is safe when you follow the steps your nurse taught you and stay alert to what the pump is telling you. Most problems are small and fixable. But some alarms mean you need to act fast. This guide walks you through the daily checks, what common alarms mean, and the exact moment to call your nurse or doctor instead of troubleshooting on your own.
Key Takeaways
- Check your pump, tubing, and catheter site every morning and before bed, looking for leaks, kinks, loose connections, and skin redness or swelling.
- Most pump alarms mean something simple like an empty medicine bag or a kinked tube, but some—like "occlusion" or "air in line"—need you to stop and call your nurse right away.
- Call your nurse or doctor immediately if you see blood in the tubing, feel sudden pain at the catheter site, run a fever, or the pump will not stop alarming after you clear the obvious problem.
- Keep your pump dry, away from extreme heat or cold, and never pull on the tubing or catheter—these are the most common causes of damage at home.
- Your nurse should give you a written list of alarms specific to your pump model and a phone number to call 24 hours a day; keep both by your pump.
Daily safety checks before and after using your pump
Every morning before your infusion starts and every evening before bed, spend two minutes looking at three things: the pump itself, the tubing, and the catheter site where the tube enters your body.
The pump: Make sure it is sitting on a flat, dry surface. Wipe the outside with a dry cloth if it has dust. Check that the power cord is plugged in firmly and the battery indicator (if your pump has one) shows it is charged. Look at the screen to see if any error messages are already showing. If the pump is beeping or displaying a warning, write down the exact words before you do anything else—your nurse will need to know what it said.
The tubing: Follow the tube from the pump all the way to where it enters your body. Look for kinks, cracks, or places where it might be pinched under your arm or caught in clothing. Check that every connection point—where the tube meets the pump, where it meets the medicine bag, where it meets your catheter—is screwed or clicked in tight. If a connection is loose, do not pull on it; call your nurse to show you how to tighten it safely.
The catheter site: Look at the skin around where the tube enters your body. It should be clean and dry. The skin should be its normal color—not red, swollen, warm, or bruised. If there is a bandage or dressing over the site, check that it is still stuck down and not peeling. If you see any oozing, pus, or blood, or if the site feels hot or tender, call your nurse the same day.
Common pump alarms and what they mean
Your pump will beep and show a message on the screen when something needs attention. Some alarms are warnings that the infusion will stop if you do not fix the problem. Others are emergencies. Here are the ones you will see most often:
Low battery: The pump is running on battery power and the charge is low. Plug it in to the wall outlet right away. This is not an emergency, but do it before the battery dies completely.
Empty bag or syringe: The medicine container is empty and the pump has stopped delivering. Check that a new bag or syringe is ready. Your nurse will have shown you how to swap it. If you are not sure, call before you try.
Kinked line or occlusion: The pump is sensing that the tubing is blocked or pinched. Stop what you are doing and look at the entire length of tubing for a kink, a twist, or a place where it is caught under something. Straighten it gently. If the alarm does not stop within 30 seconds of clearing the kink, call your nurse. Do not keep trying to restart the pump.
Air in line: The pump detected air bubbles in the tubing. This can happen when you swap medicine bags or if a connection is loose. The pump will usually clear small bubbles on its own, but if the alarm keeps going off, call your nurse. Do not try to squeeze the tubing to push air out.
Infusion complete: The pump has delivered all the medicine it was programmed to deliver. This is normal. Your nurse will have told you what to do next—usually to disconnect the pump or swap in a new bag.
Door open or pump error: The pump's access door is not closed all the way, or the pump is detecting an internal problem. Close the door firmly. If the error message stays, unplug the pump, wait 10 seconds, and plug it back in. If it still shows an error, call your nurse. Do not use the pump until you have spoken to someone.
When to call your nurse or doctor right away
Some situations cannot wait for a scheduled call or an appointment. Stop the pump and call your nurse or doctor immediately if any of these happen:
Blood in the tubing or at the catheter site: A small amount of blood when the catheter is first placed is normal, but ongoing bleeding or blood in the tubing means something is wrong. Call right away.
Sudden pain, burning, or swelling at the catheter site: This can mean the catheter has moved, the vein is inflamed, or an infection is starting. Do not wait to see if it gets better.
Fever (temperature of 100.4°F or higher): Fever during home infusion can be a sign of infection. Take your temperature and call your nurse or doctor even if you feel okay otherwise.
The pump alarm will not stop after you have cleared the obvious problem: If you have straightened the tubing, checked all connections, and the alarm is still going off, stop trying to fix it and call. Repeated alarms that do not respond to simple fixes mean the pump may need to be replaced or serviced.
Leaking medicine from any connection point: If you see liquid dripping from where the tubing connects to the pump, the medicine bag, or your catheter, call your nurse. Do not try to tighten connections yourself—your nurse needs to do this safely.
You feel dizzy, short of breath, or have chest pain: These can be signs that something is wrong with the medicine or the infusion itself. Call 911 if symptoms are severe. Call your nurse immediately if they are mild but new.
Keeping your pump safe from damage
Most pump problems at home come from things that are easy to prevent. Keep your pump away from water—do not splash it, submerge it, or use it in the shower unless your nurse has said your specific pump model is waterproof. If your pump does get wet, unplug it, dry it with a soft cloth, and call your nurse before using it again.
Do not expose the pump to extreme heat or cold. Keep it away from direct sunlight, heating vents, air conditioners, and freezers. Room temperature is safest. Do not leave it in a hot car or near a radiator.
Never pull on the tubing or catheter, even gently. If the tubing gets caught on something, stop and untangle it rather than yanking. If you feel pain when you move, the catheter may have shifted—call your nurse before moving again.
Keep the pump on a stable surface where it will not fall or tip over. If it does fall, unplug it and call your nurse before using it again, even if it looks fine. Internal damage may not be visible.
Do not try to open the pump or take it apart. If something inside seems broken, call your nurse or the pump company's support line. Repairs must be done by trained technicians.
What to keep near your pump at all times
Before you leave the hospital or clinic with your pump, ask your nurse to write down the model number and the phone number for pump support. Keep this information taped to the wall next to where you use the pump. You should also have a written list of the alarms your specific pump uses and what each one means—different pump models have different alarms, so a generic list is not enough.
Keep a notebook next to your pump and write down the time and date every time an alarm goes off, what it said, and what you did about it. This record helps your nurse spot patterns—for example, if the same alarm happens every time you move a certain way, the catheter may be in a position that causes problems. Bring this notebook to every appointment.
Have your nurse's phone number and your doctor's phone number written down in two places—one by the pump and one in your phone. Ask whether there is a 24-hour support line, because problems do not always happen during office hours. If your nurse gives you a pager number or text line, test it before you need it so you know it works.
Traveling with your pump and handling emergencies away from home
If you travel, bring your pump's power cord and a battery backup if your pump has one. Pack extra medicine bags or syringes in a cool bag (not frozen) if you will be away for more than a few hours. Bring a copy of your pump model number and support phone number, plus a list of your alarms.
If you are away from home and the pump alarms, follow the same steps: look for kinks, check connections, and clear any obvious problems. If the alarm does not stop, call your nurse or the pump company's support line from wherever you are. Do not try to drive home to fix it if you are far away.
If you are in an emergency room or hospital and the staff want to take over your pump, tell them your nurse's name and phone number. Hospital staff may not be familiar with your specific pump model, so having your home nurse available to answer questions can prevent mistakes.
Frequently Asked Questions
What should I do if the pump beeps in the middle of the night?
Turn on the light and look at the pump screen to see what alarm is showing. If it is a low battery or empty bag alarm, you can wait until morning to fix it if the pump has already stopped the infusion. If it is a kinked line or occlusion alarm, check the tubing now and call your nurse if you cannot clear it. If you are unsure whether the alarm is urgent, call your nurse—that is what they are there for, even at night.
Can I shower or bathe with my pump?
Most pumps are not waterproof, so you should not shower or bathe while wearing one. Ask your nurse whether your specific pump can get wet. If it cannot, you will need to disconnect it before bathing and reconnect it afterward. Your nurse will show you how to do this safely without introducing air or bacteria into the line.
What if I accidentally pull on the tubing and feel pain?
Stop moving immediately and call your nurse. Pain when you pull on the tubing can mean the catheter has shifted or is pressing on a nerve. Do not try to move again until your nurse has checked it. Continuing to move may cause more damage.
How often should I clean the pump?
Wipe the outside of the pump with a dry, soft cloth once a week or whenever it looks dusty. Do not use water or cleaning solutions unless your nurse has told you it is safe for your pump model. The inside of the pump should never be cleaned—that is a job for trained technicians only.
What happens if my pump breaks and I need a replacement right away?
Call your nurse or the pump company's support line immediately. They can usually send a replacement pump within hours or tell you where to pick one up. In the meantime, your nurse may be able to show you how to give your medicine by hand or switch to a different delivery method temporarily. Do not try to repair the pump yourself or use it if it is not working properly.
