You have a central venous catheter. This is a tube that goes into a vein in your chest. It will help carry nutrients and medicine into your body. It will also be used to take blood when you need to have blood tests.

You will need to make sure the skin where the catheter is placed stays healthy. This will help protect you from infection. You will need to check the skin and change the special bandages (dressings) around the site about once a week. See also: Central venous catheter-dressing change
