Access to blood. Hemodialysis needs access to blood to run high speed flow about 12-15 oz of blood per minute. This requires a larger line under the collar bone which is a temporary method or a surgery to connect the veins of arm with an artery which pours great flow of blood into the vein. The vein will get larger and can be stuck with a needle to make access to blood easy. A plastic tube may be used, a graft.
Dialysis Access. Dialysis vascular acess refers to the method by which a patient is attached to a hemodialysis machine (artificial kidney machine that filters blood). It is one method of treating kidney failure. Access to the machine is through a large plastic catheter in a vein or a fistula or graft in the arm. The arm device is more permanent and is hidden under the skin. Unlike grafts, fistulas use vein.
What's hd access. A conduit by which a patient's blood can be removed so it can be cleaned by a dialysis machine and then re-infused back into a patient. There are 3 common types: a catheter (placed into a large vein typically in the neck). The next is a graft that is sewn between an artery and a vein and the last is a fistula, where an artery and vein are sewn together. The last 2 are typically in the arm.
