Chapter 9 NIBP Monitoring (Optional)

9.1 Overview

This monitor uses the oscillometric method for measuring NIBP. It can be used for adult,
pediatric and neonatal patients.
Oscillometric devices measure the amplitude of pressure changes in the occluding cuff as the cuff
deflates from above systolic pressure. The amplitude suddenly increases as the pulse breaks
through the occlusion in the artery. As the cuff pressure decreases further, the pulsations increase
in amplitude, reach a maximum (which approximates to the mean pressure), and then diminish.
In adult and pediatric mode, the blood pressure measurements determined with this device comply
with the American National Standard for Electronic or Automated Sphygmomanometers
(ANSI/AAMI SP10-1992) in relation to mean error and standard deviation, when compared to
auscultatory measurements in a representative patient population. For the auscultatory reference,
the fifth Korotkoff sound was used to determine the diastolic pressure.
In neonatal mode, the blood pressure measurements determined with this device comply with the
American National Standard for Electronic or Automated Sphygmomanometers (ANSI/AAMI
SP10-1992) in relation to mean error and standard deviation, when compared to intra-arterial
measurements in a representative patient population.

9.2 NIBP Safety Information

1 It is forbidden to perform NIBP measurements on patient with sickle-cell disease or
under any condition where the skin is damaged or expected to be damaged.
2 For a thrombasthenia patient, it is important to determine whether measurement of
the blood pressure shall be done automatically. The determination should be based
on the clinical evaluation.
3 Ensure that the correct setting is selected when performing measurements on
children. It may be dangerous for the children to use an over pressure level.
4 Before starting a measurement, verify that you have selected a setting appropriate
for your patient (adult, pediatric or neonate.)
5 Do not apply the cuff to a limb that has an intravenous infusion or catheter in place.
This could cause tissue damage around the catheter when infusion is slowed or
blocked during cuff inflation.
6 Make sure that the air conduit connecting the blood pressure cuff and the monitor is
neither blocked nor tangled.
