Medic Spa MATRIX 100 User Manual - Measurement Principle
MEASUREMENT PRINCIPLE
This product uses the Oscillometric Measuring method to detect blood pressure.
Before every measurement, the unit establishes a “zero pressure” equivalent to the air pressure. Then
it starts inflating the arm cuff, meanwhile, the unit detects pressure oscillations generated by beat-
to-beat pulsatile, which is used to determine the systolic and diastolic pressure, and also pulse rate.
The device also compares the longest and the shortest time intervals of detected pulse waves to
mean time interval then calculates standard deviation. The device will displays a warning signal with
the reading to indicate the detection of irregular heartbeat when the difference of the time intervals
is over 25%.
