Home Blood Pressure Test
Blood pressure is displayed on a circular dial with a needle. As the pressure in the cuff rises, the needle moves clockwise on the dial. As the cuff pressure falls, the needle moves counterclockwise. As the cuff pressure falls, the reading on the gauge when blood flow is first heard is the systolic pressure. The reading on the gauge when blood flow can no longer be heard is the diastolic pressure.
