Optimization of Blood Pressure Waveforms using Adaptive, Bandpass Filters and Wavelet Methods in MATLAB

Abstract

Cardiac catheterization is one of the most important way to examine the hemodynamics of a particular patient. In this technique, the whole part of the blood pressure waveforms can be captured and recognized by the cardiologist. These types of measurements are classified by the respiration and fluid filled in catheter, by means of this technique. By this, the measurement will be more accurate, when the artifacts in the waveforms has been removed. In this report we mainly focuses upon the effects of the respiratory artifacts in which the blood pressure signals can be accompanied during the process of catheterization. In this particular project, we use four methods, they are two adaptive filters, one wavelet based method and standard bandpass filters are determined. The blood pressure waveform includes systolic and diastolic pressures. All the above mentioned categories and its methods has been implemented in MATLAB and validated.
