monitors measure blood pressure and pulse rate by using an oscillometric method, meaning the fluctuations in pressure are measured. Once the cuff is wrapped around the upper arm, the monitor is turned on and the cuff is automatically inflated. The inflation of the cuff creates pressure around the arteries inside the arm. Within the cuff is a gauge which senses the fluctuations (oscillations) in pressure. The fluctuations measured are the arteries contracting with each heart beat as a result of the pressure the cuff has placed on the arm. The monitor measures these contractions and converts the information to a digital value. That is the result displayed on the monitor screen. Once the measurement is complete the cuff will automatically deflate.
