OSCILLOMETRIC VIRTUAL INSTRUMENT FOR BLOOD PRESSURE MEASUREMENT

• Abstract:

  In this paper a simple educational model of a non-invasive blood pressure measurement device, based on the oscillometric principle is presented. The device is composed of a pressure transducer, auxiliary instrumentation for signal acquirement and digital signal processing module in the LabVIEW environment. Since the most problematic part of metrological evaluation of oscillometric devices is in proprietary algorithms of determining systolic and diastolic blood pressure, two basic algorithms are discussed. The amplitude algorithm is used for building the virtual instrument (VI). Preliminary comparisons of the built VI were done using simulated and real person's blood pressure waveform. The VI proved to be a useful tool for studying amplitude algorithms of determining systolic and diastolic pressure from the oscillations envelope.
