12.2 Safety
WARNING
z
Be sure to select the correct patient category setting for your patient before
measurement. Do not apply the higher adult settings for pediatric or neonatal
patients. Otherwise it may present a safety hazard.
z
Do not measure NIBP on patients with sickle-cell disease or any condition where
skin damage has occurred or is expected.
z
Use clinical judgment 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.
z
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.
z
If you doubt the NIBP readings, determines 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
„ Rapid blood pressure changes
„ Severe shock or hypothermia that reduces blood flow to the peripheries
„
Obesity, where a thick layer of fat surrounding a limb dampens the oscillations coming
from the artery
