Problems solved by technology

Doppler echocardiography is the most common method for clinical noninvasive measurement of SV (or CO), but its accuracy is average, and more accurate methods, such as the thermodilution method (which has become the "gold standard" for CO monitoring) Invasive detection methods can easily cause complications, or cannot provide continuous monitoring, and are expensive, so they are not suitable for daily monitoring at home

Abstract

The invention discloses a detecting method for calculating SV (stroke volume) of the heart on the basis of a pulse wave analysis method. The method can be used for performing noninvasive and continuous measurement on SV of the heart, and accordingly, simple and reliable new evaluation indexes are provided for daily monitoring for family health. According to a technical scheme, an air pump is pressurized to drive air inflation of a cuff; vibration pressure wave of the cuff is detected; signals output after detection are subjected to lowpass filtering and operational amplifier processing; the signals subjected to lowpass filtering and operational amplifier processing are subjected to digital filtering in a chip; SV is calculated with the pulse wave analysis method on the basis of the pressure wave signals subjected to digital filtering.

Description

technical field [0001] The present invention relates to a system and method in the technical field of biomedical information processing, in particular to a method for calculating heart stroke volume by collecting, processing and analyzing wrist blood pressure wave oscillation signals. Background technique [0002] Stroke volume (SV) is an important indicator of cardiac function, and cardiac output (CO) can be directly measured on the premise that the heart rate is known. Doppler echocardiography is the most common method for clinical noninvasive measurement of SV (or CO), but its accuracy is average, and more accurate methods, such as the thermodilution method (which has become the "gold standard" for CO monitoring) The invasive detection method may easily cause the risk of complications, or cannot provide continuous monitoring, and is expensive, so it is not suitable for daily monitoring at home. [0003] Therefore, it is necessary to develop a new low-cost and easy-to-ope...
