Measurement of blood pressure using wavelet transforms

This paper describes automatic blood pressure measurement for non-stationary subjects. The objectives include systolic and diastolic pressure measurements for a subject at rest, walking with arm held, and walking with arm swinging. The wavelet transform method was employed to process the blood pressure signals obtained using the auscultatory method. Detection techniques were developed to de-noise the signal, identify the blood pressure pulses and to determine the systolic and diastolic points
