Chapter 7: Noninvasive Blood Pressure
(NIBP)
Operation - NIBP
Note: This feature is optional on Rad-97 devices.
Rad-97 works by noninvasively monitoring the amplitude of cuff pressure changes during cuff
deflation to determine arterial blood pressure. The cuff pressure is first elevated above the
patient's systolic blood pressure level. The cuff will then begin to deflate at a certain rate. The
initial rise in the amplitude of pressure fluctuations during cuff deflation corresponds closely
to the systolic blood pressure. As the cuff is further deflated, the pressure fluctuations
increase in amplitude until a peak is reached which is usually referred to as the mean arterial
pressure (MAP). As cuff deflation continues, the diastolic pressure can be determined based
upon the rapidly diminishing amplitude of the pressure fluctuations.

The NIBP display on the Main Screen of Rad-97 consists of different areas.
