Incorrect Arm Positioning Skews Blood Pressure Readings

A new study reveals that improper arm positioning during blood pressure checks may lead to widespread misdiagnosis of hypertension.

Researchers found that blood pressure readings can vary significantly depending on arm positioning, potentially leading to misdiagnosis.
The study, published in JAMA Internal Medicine, showed that readings are most accurate when the arm is supported on a hard surface at heart level.
Improper arm positions, such as resting on a lap or hanging by the side, can artificially raise systolic readings by 4 to 7 mm Hg.
These inaccuracies could result in unnecessary hypertension treatment for millions of Americans, according to the study's authors.
Experts emphasize the importance of correct measurement techniques both in clinical settings and at home to ensure accurate blood pressure management.
