Every time your heart beats, it pushes blood into your arteries, creating pressure in them. (Read about “The Heart & Cardiovascular System”) This is what keeps blood moving through your body. (Read about “Vascular System”) According to NHLBI, most of us have probably had our blood pressure measured at some point, using what’s called a sphygmomanometer.
A blood pressure cuff is wrapped around your upper arm and inflated to stop the blood flow in your artery for a few seconds. A valve is opened and air is then released from the cuff so the blood can start flowing again. The sounds of your blood rushing through an artery are heard through a stethoscope.
