HOW UA-774 WORKS
LifeSource™ Blood Pressure Monitors are easy to use, accurate and digitally display full measurement readouts. Our technology is based on the “oscillometric method” — a noninvasive blood pressure determination. The term “oscillation” refers to any measure of vibrations caused by the arterial pulse. Our monitor examines the pulsatile pressure generated by the arterial wall as it expands and contracts against the cuff with each heartbeat.
The cuff is inflated until the artery is fully blocked. The inflation speed is maximized and the pressure level is optimized by the device. The monitor takes measurements while the cuff is both inflating and deflating. This results in a faster measurement providing greater comfort to the user.
