can you use a port for dialysis
3 types of vascular access ports used in hemodialysis. Hemodialysis refers to a method for cleaning the blood. Dialysis functions to removemetabloic waste products such as potassium, urea from the blood during renal failure. Additionally, dialysis may be used to remove other chemical toxins from the bloodstream in cases of overdose. In the case of renal failure, patients may undergo dialysis treatments three times a week for 3 to 4 hours. Hemodialysis requires a vascular access site. This is an arterial and venous site on your body from which your blood is removed and returned after it is filtered by the dialysis machine.
