Abstract :
An application of time-sequenced adaptive filtering structure to reduction of the pulmonary artery pressure artifact is presented. The authors use the pulmonary artery pressure (PAP) signal for the input and an rectified sine wave signal contained correlated information (but not identical in waveshape) for the reference input. A filtered PAP signal from beat to beat provides stable systolic and diastolic pressure information. This filtering system is applicable to a microprocessor-based bedside monitor which requires simultaneous PAP monitoring.<>
