Rest → repeat → record

Use a correct-sized cuff on the non-access arm, supported posture, and rest when feasible. Repeat an unexpected value while assessing symptoms. Record the actual repeated pressure, pulse, position, timing, and medicines taken.

Separate urgency from trend

Chest pain, severe dyspnea, neurologic deficit, confusion, or poor perfusion with abnormal pressure needs urgent assessment. An asymptomatic high reading still needs confirmation and follow-up, with timing based on clinical context.

Track the dialysis pattern

Record the lowest SBP each treatment. A rise >10 mmHg from pre- to postdialysis into the hypertensive range in at least 4 of 6 sessions is a review signal. Pair it with weights, removal, symptoms, medication timing, and home BP.

Bring readings from home

Home or ambulatory measurements can add information that chair readings miss. Confirm device technique, dates, symptoms, and the clinician’s individualized goals; avoid applying one universal dialysis blood-pressure target.

Keep medication decisions clear

Reconcile the actual antihypertensive schedule and recent hospital changes. Do not independently add doses, hold all medicines, or raise ultrafiltration solely because a predialysis measurement is high.

Ask for a written action plan

Give repeated readings, symptoms, home log, recent weights, and treatment tolerance. Confirm the patient’s call thresholds and medication schedule. A high chair reading alone does not authorize extra antihypertensive medicine or faster fluid removal.
