TERMINOLOGY FOR NIBP
Oscillometry
The oscillometric method of blood pressure measurement is a non-invasive method that
monitors the amplitude of cuff pressure changes during cuff deflation to determine
arterial blood pressure. The cuff pressure is first elevated above the patient systolic
blood pressure level and the cuff begins to deflate at a certain rate. The initial rise in
amplitude of these pressure fluctuations during cuff deflation corresponds closely to the
systolic blood pressure. As the cuff is further deflated, these 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.
Thus systolic, MAP and diastolic blood pressures can be accurately obtained by
supervising the pressure fluctuations while controlling the cuff deflation rate.
mmHg
Millimeters of Mercury, which is the most common unit of measure for pressure in non-
invasive blood pressure.
NIBP
Non-invasive blood pressure.

Patient Populations
There are three major patient groups which are formally defined as neonate (up to 28
days), pediatric (29 days to 12 years) and adult (13 years and older).
