BACKGROUND: Non-invasive continuous blood pressure monitoring can provide an important reference and guidance for doctors wishing to analyze the physiological and pathological status of patients and to prevent and diagnose cardiovascular diseases in the clinical setting. Therefore, it is very important to explore a more accurate method of non-invasive continuous blood pressure measurement. OBJECTIVE: To address the shortcomings of existing blood pressure measurement models based on pulse wave transit time or pulse wave parameters, a new method of non-invasive continuous blood pressure measurement-the GA-MIV-BP neural network model-is presented. METHOD: The mean impact value (MIV) method is used to select the factors that greatly influence blood pressure from the extracted pulse wave transit time and pulse wave parameters. These factors are used as inputs, and the actual blood pressure values as outputs, to train the BP neural network model. The individual parameters are then optimized using a genetic algorithm (GA) to establish the GA-MIV-BP neural network model. RESULTS: Bland-Altman consistency analysis indicated that the measured and predicted blood pressure values were consistent and interchangeable. CONCLUSIONS: Therefore, this algorithm is of great significance to promote the clinical application of a non-invasive continuous blood pressure monitoring method.
