Measuring blood pressure accurately

Accurately measuring blood pressure is imperative for diagnosis and control of hypertension. There is a range of devices and methods for measuring blood pressure that each have advantages and limitations. To ensure accuracy of blood pressure measurement and hypertension diagnosis, clinicians and patients should use an accurate and validated blood pressure measurement device, an appropriately sized cuff, and take several measurements rather than only one measurement, using a standardised measurement protocol. Out-of-clinic measurement, using an ambulatory or home blood pressure monitoring device, depending on patient preference, should be used to confirm diagnosis and guide treatment of hypertension. There are emerging new technologies for blood pressure measurement (e.g. wearable technologies) that are yet to be validated and have the potential to improve blood pressure monitoring and patient self-management.
