Magic Care Automatic Arm Blood Pressure Monitor with Large LCD & Carry Case
Comfortable measurement
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%.
Highly accurate arm sphygmomanometer clinically validated
