HOW Z-46 WORKS
Z-46 uses 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. After the cuff inflates
to block your blood in the artery, the deflation process starts. During
the deflation of the wrist cuff, the monitor 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
Z-46 will determine the systolic and
diastolic pressures for you, and your pulse rate is detected at the same
time.
