4.6 Measurement principle
4.6.1 NIBP
NIBP (Non-Invasive Blood Pressure) is an indirect method for measuring blood pressure.
The NIBP parameter conforms to EN 1060-1:1995 Specification for Non-invasive
sphygmomanometers.
The NIBP measurement is performed according to the oscillometric measuring principle. The
cuff is inflated with a pressure slightly higher than the presumed systolic pressure, and
deflated at a speed based on the patient’s pulse, collecting data from the oscillations caused
by the pulsating artery. Based on these oscillations, values for systolic, mean, and diastolic
pressures are calculated.
The following parts are necessary for the NIBP measurement:
•
E-PSM(P)W module
•
twin hose (adult or infant model)
•
blood pressure cuffs (various sizes)
4.6.2 ECG
Electrocardiography analyzes the electrical activity of the heart by measuring the electrical
potential produced with electrodes placed on the surface of the body.
ECG reflects:
•
electrical activity of the heart
•
normal/abnormal function of the heart
