7 common mistakes in BP measurement

Misreading true blood pressure by even 5 mm Hg has the potential to mislabel someone as having high blood pressure, resulting in medication the person doesn’t need. It also can result in the opposite, in which a patient fails to get necessary medical treatment. American Heart Association (AHA) highlights 7 common mistakes in BP measurement ▪ Putting the cuff over clothing, rather than a bare arm, can add 10-40 mm Hg to a measurement. ▪ Use correct cuff size. ▪ Having a full bladder can tack on 10-15 mm Hg. ▪ Talking or having a conversation: an additional 10-15 mm Hg. ▪ Failing to support the arm at heart level can add 10 mm Hg. ▪ An unsupported back can increase a measurement by 5-10 mm Hg. That same range applies to feet left dangling from an exam table or high chair. ▪ Crossing legs means an extra 2-8 mm Hg. (Source: AHA)
