Many people may find a wrist cuff easier to apply than a traditional arm cuff. Using the wrong cuff size could result in inaccurate measurements. If your wrist measurement is outside the stated size range, it is necessary to use an arm style cuff monitor. People with hypertension, arteriosclerosis or diabetes should consult their physician about monitoring blood pressure at the wrist.
