Lumiscope 1140 - Step Valve Technology

More Accurate by Using Step Valve
Technology
The new Lumiscope 1140 Blood Pressure Monitor
incorporates cutting-edge Step Valve Technology,
resulting in greater measurement accuracy. Step
valve technology uses an electronic valve system as
opposed to the traditional mechanical valve system,
allowing the monitor to analyze oscillations during
measurement and adjust cuff pressure accordingly.
Adjustments in cuff pressure occur in steps and
result in an audible ticking as the valve releases air
from within the cuff.
Releasing pressure in steps allows the monitor to
analyze oscillations within the cuff and evaluate them
for accuracy. When the monitor does not detect
oscillations for a particular step, it releases air
pressure.
If the monitor detects oscillations, it will continue to
evaluate at that particular step until it confirms the
accuracy of those oscillations.
The monitor's ability to detect and analyze
oscillations at each step and adjust cuff pressure
accordingly results in the monitor's increased
measurement accuracy.
