Blood pressure moves throughout the day. That is normal. What matters for you and your doctor is the pattern across days and weeks — and a pattern is only useful if every reading was taken the same way.
Before you measure
Sit quietly for five minutes. No caffeine, smoking, or exercise in the previous 30 minutes. Empty your bladder. Remove tight clothing from the arm.
Position
Sit in a chair with back support, feet flat, legs uncrossed. Rest your arm on a table so the cuff is level with your heart. Palm up, arm relaxed.
Taking the reading
Press START and stay still. Do not talk. Let the cuff inflate and deflate on its own. Take two readings one minute apart and record both — or let the app do it.
Home readings are for monitoring. Discuss unusual results with your physician and never change medication on your own.
