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 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.
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
Do not use the NIBP cuff on the arm on the side of a mastectomy.
z
NIBP reading can be affected by the measurement site, the position of the
PATIENT, exercise, or the patient's physiologic condition. If you doubt the NIBP
measurements, determine the patient’s vital signs by alternative means and then
verify that the monitor is working correctly.
z
Continuous CUFF pressure due to connection tubing kinking may cause blood flow
interference and resulting harmful injury to the patient.
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
