How does a bp tester works?

Assuming by 'bp' you mean blood pressure... The 'standard' tester works like this - An inflatable cuff is wrapped around the upper arm. The medic listens to the pulse in your arm as they slowly inflate the cuff with air. The amount of pressure in the cuff is displayed on a dial - and the medic notes this pressure when the pulse stops. A release valve on the cuff is slowly opened and the cuff deflates. Again - the medic listens for the pulse returning to your arm - and notes the pressure. This gives the pressure readings (for example 90/40)
