Citizen CH-453 Digital B.P Apparatus is most commonly measured via a sphygmomanometer, which historically used the height of a column of mercury to reflect the circulating pressure. Citizen Upper Arm Blood Pressure Monitor (CH–453) Blood pressure values are generally reported in millimeters of mercury (mmHg), though aneroid and electronic devices do not contain mercury.
When attaching the cuff, adjust the position of the cuff so that the blue marker is located in the center of your arm and the hem of the cuff is 1-2 cm for Cuff / 2-3 cm for large cuff above your elbow. In order to obtain a proper reading, you should urinate and then remain relatively still for 10 to 15 minutes prior to measurement.
DO NOT place too much emphasis on the results of one measurement. Keep a continuing record of your blood pressure variations. A complete picture can only be obtained from a large number of readings and comparing them.
