How is blood pressure measured?
Last updated on: 07 September 2017
Blood pressure is the force that the blood exerts on the walls of your artery as the heart pumps it through the body. This force is measured in mm Hg (millimeters mercury).
There are different methods and devices that can be used to measure blood pressure. Most commonly devices used today are automated blood pressure monitors using the Oscillometric method.
In the Oscillometric method, signals from the pulsation of the blood vessel are detected and transmitted by the cuff to a pressure sensor. These pressure signals are in turn, converted to electrical signals for us to read on the monitor.
