Caring for a Central Line (CVC) at Home or in Rehab
A plain-language guide to caring for a central line (non-tunneled central venous catheter) at home or in rehab — keeping it clean and dry, protecting it, recognizing problems, and when to call for help.
If you are leaving the hospital — for home or a rehab or skilled nursing facility — with a central line (a non-tunneled central venous catheter, or CVC), this guide explains how to keep it clean and safe and how to recognize a problem early.
A non-tunneled central line is usually a shorter-term device. If you have a PICC line, implanted port, or tunneled (Hickman/Broviac) catheter, follow the guide for that device — they are cared for differently.
What a central line is
A central line is a thin, flexible catheter placed into a large vein in your neck, chest, or groin, with its tip resting in a large vein near the heart. It lets your care team give medicines, fluids, and nutrition, and draw blood, without repeated needle sticks. Because the tip sits in a major vein, keeping it clean and protected is very important.
Your daily central line care routine
- Keep the dressing clean, dry, and sealed on all edges.
- Wash your hands before touching the line or its connections.
- Keep clamps closed and caps on every port when not in use.
- Flush only as instructed, never forcing it.
- Check the site and how you feel every day.
Keeping it clean and dry
The clear dressing is your main protection against infection — keep it intact and dry. Most people with a non-tunneled central line are told not to shower over the site; use sponge baths and keep the area dry. Never swim or submerge the line. If the dressing loosens or gets wet underneath, contact your care team for a fresh sterile dressing.
Warning signs — when to call your care team
- Fever or chills
- Redness, swelling, warmth, drainage, or pain at the site
- Swelling of the face, neck, or arm
- A line that will not flush or a leaking connection
Emergencies — call emergency services
- The line is cut, broken, or pulled out — clamp or fold it closed, lie on your left side, and call for help (air can enter the vein)
- Sudden shortness of breath or chest pain
