6 How the 1140 Works

Your model 1140 uses the oscillometric method to detect your blood pressure. Before the cuff starts inflating, the device will establish a baseline cuff pressure, which is equivalent to the air pressure. The measurement of your blood pressure is based on this baseline pressure. After the cuff inflates to block your blood in the artery, the deflation process starts. During the deflation of the wrist cuff, your 1140 is detecting the pressure oscillations generated by the beat-to-beat pulsatile. Any muscle movement during this period of time will cause measurement error. After detecting the amplitude and the slope of the pressure oscillations during the deflation process, your 1140 will determine the systolic and diastolic pressures for you, and your pulse rate is detected at the same time.
