13.4 Measurement Methods

There are four methods of measuring NIBP:
Manual - measurement on demand. Manual is the default setting in Ward round and
spot-checking mode.
Auto - continually repeated measurements (between 1 and 480 minute adjustable interval).
After the first measurement starts manually, the monitor will automatically measure NIBP as
preset interval. Auto is used in monitor mode only.
Continual- the measurement will run consecutively in five minutes with intervals of 5
seconds, then the monitor enters manual mode or auto mode.
Average – between 1 and 5 minute adjustable AVG interval, measurement will run as
specified AVG times (3 or 5 times are optional), then gets average value. Average is used in
Ward round or spot-checking mode only. After finishing average measurement, the monitor
enters manual mode.
To change Measure Mode, Interval, AVG Measurement Interval and AVG Measurement
Times, please select NIBP Setup > Function.
Prolonged non-invasive blood pressure measurements in Auto mode may be associated
with purpura, ischemia and neuropathy in the limb wearing the cuff. When monitoring a
patient, examine the extremities of the limb frequently for normal color, warmth and
sensitivity. If any abnormality is observed, stop the blood pressure measurements.
