Starting dialysis is a significant step, and it's natural to feel anxious or uncertain. At Avitus, we want to make your first experience as comfortable as possible. This guide will walk you through exactly what to expect so you can arrive feeling prepared and confident.
When you arrive, our reception staff will greet you and guide you to your treatment station. A nurse will check your weight (to determine how much fluid to remove), blood pressure, temperature, and pulse.
You'll be seated in a comfortable reclining chair. Take a moment to settle in — adjust the chair, get a blanket if you'd like, and set up any entertainment you brought. Our nurses will explain each step as they prepare you for treatment.
The nurse will clean your access site (fistula, graft, or catheter) and insert the needles. You may feel a brief pinch, similar to having blood drawn. Once connected, your blood will flow through the tubing to the dialyzer (artificial kidney), where it's cleaned, and then returns to your body.
Your treatment will last approximately 4 hours. During this time:
When your treatment is complete, the nurse will return your blood and disconnect you from the machine. They'll apply pressure to the needle sites until any bleeding stops. Your weight and vital signs will be checked again.
Starting dialysis is just the beginning of your journey with us. Our entire team — doctors, nurses, dietitians, and social workers — is dedicated to helping you live well on dialysis. Welcome to the Avitus family.
