Effects of cuff size on the accuracy of blood pressure readings

About The Study: Using a regular blood pressure (BP) cuff size for all individuals regardless of arm size resulted in strikingly inaccurate BP readings with an automated device in this randomized crossover trial including 195 adults. This is particularly concerning for settings where one regular BP cuff size is routinely used in all individuals, regardless of arm size. A renewed emphasis on individualized BP cuff selection is warranted.
