Vital Signs Monitor User’s Manual
Chapter 7-1
The monitor uses the oscillometric method for measuring NIBP. It is applicable
for adult, pediatric and neonatal patients. The method of oscillometric indirectly
estimates the systolic and diastolic pressures within the blood vessels by measuring
the change of the pressure within blood pressure cuff along with the volume of the
arteries and calculates the average pressure.
The NIBP measurement is suitable for use in the presence of electrosurgery and
during the discharge of a cardiac defibrillator according to IEC 60601-2-30:1999/EN
A physician must determine the clinical significance of the NIBP measurement.
Check the patient category before monitoring. Incorrect settings may
result in some risk for patient safety. Higher adult setting is not suitable
for pediatric and neonatal patients.
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 decide whether to perform frequent Auto BP
measurements on patients with severe blood clotting disorders because of
the risk of hematoma in the limb fitted with the cuff.
Use clinical judgement to decide whether to perform Auto BP
measurement on the patients of thrombasthemia.
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 measurements, check the patient’s vital signs by
other device, and then check the monitor.
