12.2 Safety
WARNING

Be sure to select the correct patient category setting for your patient before measurement. Do not measure
NIBP on patients with sickle-cell disease or any condition where skin damage has occurred or is expected.

Use clinical judgement to determine whether to perform frequent unattended blood pressure
measurements on patients with severe blood clotting disorders because of the risk of hematoma in the limb
fitted with the cuff.

Do not use the NIBP cuff on a limb with an intravenous infusion or arterial catheter in place. This could cause
tissue damage around the catheter when the infusion is slowed or blocked during cuff inflation.

If you doubt the NIBP readings, determine the patient’s vital signs by alternative means and then verify that
the monitor is working correctly.
12.3 Measurement Limitations
Measurements are impossible with heart rate extremes of less than 40bpm or greater than 240bpm, or if the patient is
on a heart-lung machine.
The measurement may be inaccurate or impossible:

If a regular arterial pressure pulse is hard to detect

With excessive and continuous patient movement such as shivering or convulsions

With cardiac arrhythmias

With rapid blood pressure changes

With severe shock or hypothermia that reduces blood flow to the peripheries

With obesity, where a thick layer of fat surrounding a limb dampens the oscillations coming from the artery
12.4 Measurement Methods
There are three methods of measuring NIBP:

Manual: measurement on demand.

Auto: continually repeated measurements at set intervals.

STAT: continually rapid series of measurements over a five minute period, then return to the previous mode.
