In every significant patient interaction, whether ambulatory or hospital based. Always obtain two or
more readings from the same arm, with patient supine or seated. Then record the average value. If diastolic
readings differ by more than 5 mmHg, take additional measurements until a stable pressure is reached.
Measure blood pressure in both arms at the first visit, and then use the arm with the higher pressure thereafter (the arm with the lower pressure is abnormal). When indicated, also measure the pressure in the lower extremities and/or in different positions (supine versus standing)
