AHA’s list of BP measuring mistakes

New Delhi, September 16,2018 :

Any of these errors may elevate your BP reading by several points (even as much as 10 points, in some cases), although they are generally not additive.

• Having a full bladder. An uncomfortably full bladder might increase your reading.
• Having no support for your back or feet. Slouching or dangling your feet when sitting can increase your reading. Make sure you sit in a chair with your back supported and feet flat on the floor or a footstool. At home, don’t sit on a sofa or reclining chair.
• Sitting with crossed legs. Crossing your legs squeezes the large veins in your legs, which may raise the reading slightly.
• Not supporting your arm.  Your arm should be totally relaxed so your biceps (upper arm) muscle isn’t contracted. Be sure to position your arm on a chair or counter, so that the blood pressure cuff is level with your heart. Also, don’t clench your fist.
• Wrapping the cuff over clothing. Depending on the thickness of the fabric, putting a cuff over clothing can boost the reading by quite a bit. Wear a short-sleeved shirt (along with easily removable layers, if you’re chilly in the doctor’s office) so the cuff is placed on your bare arm.
• Using a cuff that’s not the correct size. Many people need a large-sized cuff. Using one that’s too small will be uncomfortable and may elevate your pressure by several points. Note that models with upper-arm cuffs are more reliable than those that fit on the wrist.
• Engaging in conversation. Chatting during the measurement — or even actively listening — can boost blood pressure.
