Kindly let me know if it is true that certain arm positions during Blood Pressure checks may lead to inaccurate results

Yes, in a new study, researchers say different arm positions can produce different blood pressure readings. They report that blood pressure readings taken when the arm is resting on a hard surface such as a desk are slightly lower than when the arm is resting in a person’s lap or hanging by their side.

Experts say inaccurate higher readings could lead to a hypertension misdiagnosis and unnecessary interventions like medication. If a person’s actual top number on a blood pressure reading is 115, an incorrect arm position could increase that mark to more than 120, pushing them into the category of elevated blood pressure. If someone’s actual measurement is 126, a misreading could bump that number above 130 and into the category of stage 1 hypertension.

Experts say not only would a person be misdiagnosed with high blood pressure, they could also be prescribed unnecessary medication.

Accurate blood pressure readings at home are equally important. Patients should feel empowered to ask for a repeat blood pressure measurement if the measurement being obtained is significantly different than previously obtained.
