Vascular access (often called just "access") is needed for you to get hemodialysis. Using the access, blood is removed from your body, cleaned by a dialyzer, then returned to your body.
Usually the access is put in a person's arm. But it can also go in your leg. Depending on the type of access, it takes a few weeks to a few months to get an access ready for hemodialysis.
Taking good care of your access helps make it last longer.

Keep your access clean. Wash the access with soap and water every day to decrease your risk of infection.
Do not scratch your access. If you scratch open your skin at the access, you could get an infection.
To prevent infection:
To keep blood flowing through the access:
Check the pulse in your access arm. You should feel blood rushing through that feels like a vibration. This vibration is called a "thrill."
Have the nurse or technician check your access before every dialysis.
