Clinical monitoring comes first

A functioning fistula or graft requires a usable flow pathway and healthy overlying tissue. Physical examination complements machine and surveillance data.

Inspect before treatment

Look for swelling, redness, drainage, aneurysmal change, skin compromise, and hand ischemia. Ask about pain and changes since the previous treatment.

Assess the flow pattern

Palpate pulse and thrill and listen to the bruit according to training. Unexpected changes may indicate inflow or outflow problems.

Cannulate with a plan

Use trained technique and the prescribed approach, protect usable segments, and avoid damaged or infected areas. Maturation is a clinical assessment, not a date alone.

Report dysfunction promptly

Prolonged bleeding, difficult cannulation, abnormal pressures, reduced delivery, or changed examination should trigger the established evaluation pathway.

Preserve the access life

Repeated trauma and unrecognized dysfunction accumulate. Document findings and communicate across the team so trends are acted on.
