16 Monitoring Noninvasive Blood Pressure (NIBP)
16.1 NIBP Introduction
The monitor uses the oscillometric method for measuring the non-invasive blood pressure (NIBP). NIBP
measurement is based on the principle that pulsatile blood flow through an artery creates oscillations of the
arterial wall. The oscillometric device uses a blood pressure cuff to sense these oscillations that appear as tiny
pulsations in cuff pressure. The 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. The oscillometric
method measures the mean pressure and determines the systolic and diastolic pressures.
The NIBP module is integrated into the MPM module. NIBP monitoring is intended for adult, pediatric, and
neonatal patients.
• Blood pressure measurements determined with this device are equivalent to those obtained by a
trained observer using the cuff/stethoscope auscultatory method or an intra-arterial blood pressure
measurement device, within the limits prescribed by the American National Standard: manual,
electronic, or automated sphygmomanometers.
• NIBP measurement can be performed during electro-surgery and discharge of defibrillator.
