HOW UB521 WORKS

BEFORE YOU START

LifeSource

Blood Pressure Monitors are easy to use, accurate and display

clear digital measurements. Our technology is based on the “oscillometric

method”. The term “oscillation” refers to the measure of vibrations caused

by the arterial pulse and is a non-invasive method to determine blood

pressure.

Our monitors examine the pulsatile pressure generated by the arterial wall

as it expands and contracts with each heartbeat against the monitor’s cuff.

This monitor measures your blood pressure while the cuff is inflating.
