Suppression of respiratory interference in oscillometric waveform using wavelet ridge method

摘要: Effects of breathing signal in the oscillometric waveform (OMW) can greatly degrade accuracy systolic and diastolic readings for blood pressure measurement. This paper proposes a simple method based on wavelet ridge (WR) to suppress respiratory interference OMW order extract accurately its envelope which is very important measurement method. The results simulated signals real show that it efficiently effects smooth envelope.
