Measure Your Patient’s Arm
Wrap a tape measure around the patient’s bicep, at mid-arm to determine the arm circumference (typically measured in cm).
Select a Cuff Size Based on Arm Circumference
The ideal cuff bladder length is ≥ 80 percent of the patient’s arm circumference. The ideal cuff bladder width is ≥ 40 percent of the patient’s arm circumference.
