Abstract
This application provides a method and device for assessing blood volume status based on multi-parameter fusion and virtual calibration, belonging to the field of smart healthcare. The method includes: acquiring the patient's baseline parameters, treatment parameters, and circulatory parameters as basic features; constructing features based on the baseline parameters, treatment parameters, and circulatory parameters to obtain physiological features; constructing sample features based on the physiological features; and importing the sample features into a pre-trained blood volume index prediction model to obtain the patient's blood volume index. This method constructs physiological feature data from basic data, constructs sample features based on the physiological feature data, and then calculates the patient's blood volume.
