Non-Invasive Blood Pressure
Overview
The monitor can acquire and process non-invasive blood pressure (NBP) signals and display the results
for neonatal, pediatric, and adult patients. NBP accuracy was established using intra-arterial blood
pressure monitoring as a reference (within the limits prescribed by the Association for Advancement of
Medical Instrumentation, Electronic Automated Sphygmomanometers). Accuracy testing references used
the femoral artery for adults, and the umbilical, brachial, radial, or femoral arteries for pediatric and
neonate patients. NBP measurements for accuracy testing occurred on the same limb. NBP effectiveness
for pregnant and pre-eclamptic patients has not been established according to ISO 81060-2.
The accuracy is compromised with patients having dysrhythmias, arterial sclerosis, experiencing seizures,
or any type of cardiac or vascular malformation which results in an abnormal arterial waveform. Blood
pressure measurements are determined by the oscillometric method. Once the cuff has been inflated to
occlude the blood flow through the patient’s limb, the cuff is deflated in a controlled manner. As the cuff
pressure decreases, the oscillations increase in amplitude and then decrease as blood returns to normal
flow. From this change in amplitude, the mean arterial blood pressure can be directly determined and
systolic (S) and diastolic (D) blood pressures derived.
