Chapter 14 NIBP Monitoring
14.1 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.
14.2 NIBP Safety Information
1
You must not perform NIBP measurement on the patients with sickle-cell disease or
on the patients whose skin is damaged or anticipated 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 mode is selected when performing measurements on children
or neonates. (For more information, please refer to the sections about menu setting.)
Incorrect patient mode setting could do harm on patients. It may be dangerous for
children and neonates to use an over pressure level.
4
The equipment is applicable in electrosurgery.
5
The equipment can provide protective means to prevent the patient from being
burned when used with HF SURGICAL EQUIPMENT.
6
The equipment can protect against the effects of the discharge of a defibrillator.
7
The continuous measuring and calibration can not be operated on neonatal or
pediatric patients, nor in AUTO measurement mode.
8
Continuous use of the automatic measuring mode for short intervals may lead to the
discomfort of patient.
9
Please do select the correct patient mode and the suitable cuff in case any damage
will be caused by wrong operation or over pressure.
