How Hemodialysis Works
A simple path through the treatment—not machine-operation instructions.
Access connects you to the bloodlines
Your fistula, graft, or catheter allows blood to move between your body and the dialysis circuit.
Blood travels to the dialyzer
A pump moves blood through the extracorporeal tubing toward the dialyzer—the filter used during treatment.
The dialyzer does the filtering work
Across the dialyzer membrane, waste and fluid can move according to the treatment process while blood stays within the blood pathway.
The machine monitors the treatment
The dialysis machine tracks pressures, fluid removal, dialysate conditions, alarms, and other treatment information that staff use to monitor the session.
Blood returns to you
After passing through the dialyzer, blood returns through the venous side of the circuit. At the end, the team completes the disconnect and rinseback process as appropriate.
This overview explains general concepts. Dialysis equipment is operated and treatment settings are managed by trained clinical staff.
