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.
