Blood pressure measurement: arm circumference and cuff size availability.

To avoid inaccurate blood pressure (BP) readings, the American Heart Association (AHA) recommends cuff width (CW) encircling 40% of the arm circumference (AC) and cuff length at least 80-100%. This study aimed to identify inpatients AC, the corresponding cuff size and the cuff size availability. In total, 81 AC were measured in the right arm.
