Correct blood pressure measurements are essential to diagnosing and treating high blood pressure. Accordingly, a specific set of techniques and procedures have been developed which describe the proper method for obtaining the most accurate blood pressure readings possible. Because research has shown that medical professionals often do not completely follow these guidelines, it is important for the patient to be able to identify when proper protocol is not being followed.

Choose the Proper Cuff Size


One of the most important factors that can influence the accuracy of blood pressure readings is the size of the blood pressure cuff that is used.

The official guidelines specify the following cuff sizes:
· Arm circumference 22 to 26 cm, 'small adult' cuff, 12 x 22 cm
· Arm circumference 27 to 34 cm, 'adult' cuff: 16 x 30 cm
· Arm circumference 35 to 44 cm, 'large adult' cuff: 16 x 36 cm
· Arm circumference 45 to 52 cm, 'adult thigh' cuff; 16 x 42


Accurate Blood Pressure Readings Require Proper Positioning

Proper positioning is vital in obtaining accurate blood pressure readings.
In general, blood pressure should be measured while you are seated comfortably. The arm being used should be relaxed, uncovered, and supported at the level of the heart. Only the part of the arm where the blood pressure cuff is fastened needs to be at heart level, not the entire arm.


Multiple Blood Pressure Readings Should Be Taken

One blood pressure reading is not enough to get an accurate measurement. While the specifics of how many readings are necessary can change based on many factors, the essential need for multiple measurements does not.
