METHOD FOR MEASURING ARTERIAL PRESSURE Russian patent published in 1998 - IPC

FIELD: medicine. SUBSTANCE: method involves changing pressure in cuff, recording signal, proportionally changing cuff pressure during decompression period, and selecting oscillation signal. The oscillation signal is differentiated, negative value segments are selected from the differentiated signal, their envelope and approximating envelope function as polynomial of the fifth power are built. The function is differentiated and derivation function minimum value is used to determine the moment for systolic pressure measurement to be taken. The maximum value is used to determine the moment for diastolic pressure measurement to be taken. EFFECT: enhanced accuracy and noise immunity of the method. 1 dwg
