The Impact of Blood Pressure Cuff Size on Accuracy of Readings
The fit of an arm cuff used to measure blood pressure can significantly affect the accuracy of readings, especially for individuals with larger arms, according to a study published in JAMA Internal Medicine. Researchers found that using a standard cuff size for all individuals led to "strikingly inaccurate" readings. Properly fitting cuffs are crucial to avoid over-treatment or under-treatment, which can increase the risk of heart attack, stroke, and other health complications. It is recommended to individualize blood pressure cuffs based on arm size and consult with a healthcare provider to ensure accurate readings. Other factors, such as activity level, positioning, and anxiety, can also impact blood pressure readings.
