- Begin by measuring the patient’s mid upper arm circumference.
- Using the sizing chart below, determine what size cuff should be used based on the measurement reading.
If a patient’s cm measurement is overlapping between sizes, default to the larger cuff if width is appropriate.
- Place the artery mark located on the cuff over the patient’s brachial artery.
- Wrap the cuff snugly and securely, allowing space for two fingers to fit between patient and cuff.
Common sources of error in blood pressure monitoring¹
The American Heart Association recommends that a cuff bladder width be 40% of the arm circumference and that a cuff bladder length be 80% of the arm circumference.¹
