Abstract

The invention discloses a system and method for central arterial pressure waveform reconstruction based on CNN-BiLSTM, and relates to the technical field of artificial intelligence and medical device research and development. The invention includes a data acquisition control module, a radial artery pressure measurement module, a fingertip arterial pressure measurement module, a data processing module, a central arterial pressure calculation module and a data display module. The invention does not need to manually extract features, and does not need to establish an intermediate simulation model and its parameter estimation, and automatically establishes an end-to-end reconstruction model of peripheral blood pressure and central arterial pressure, which effectively improves the reconstruction accuracy of the central arterial pressure waveform. The improvement of the neural network structure improves the model's ability to learn waveform features. Compared with other artificial neural networks, this network has a stronger learning ability for blood pressure waveforms and better reconstruction of central arterial pressure.

Description

technical field [0001] The invention belongs to the technical field of artificial intelligence and medical device research and development, and in particular relates to a system and method for central arterial pressure waveform reconstruction based on CNN-BiLSTM. Background technique [0002] Cardiovascular disease is an important cause of human death and disability. In recent years, with the increase in obesity, the risk of cardiovascular disease has been increasing. Accurately grasping the health status of the cardiovascular system of patients can provide immediate assistance to patients, thereby effectively reducing the incidence and mortality of cardiovascular events. As the lateral pressure of blood on the vessel wall of the ascending aortic root, CAP is more closely related to cardiovascular events than peripheral arterial pressure, and is independently related to some cardiovascular events. Therefore, the detection of CAP is of great significance in the prediction, ...
