NIBP technologies. The Advantage series of OEM NIBP technologies provides the simplicity of the
oscillometric technique of acquiring blood pressure with the most reliable, flexible and clinically accurate
modules in the industry.
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.
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).
