The invention relates to the technical field of medical monitoring, in particular to a multi-source data integration grading early warning method and system for hand surgery vascular crisis. The invention discloses a multi-source data integration grading early warning method for hand surgery vascular crisis. The method comprises the following steps: S1, synchronously collecting tissue oxygen saturation, an original and uninjured side temperature difference value, behavioral environment data and clinical auxiliary data of a sentinel area through a multi-source sensor; s2, establishing a behavior recognition algorithm model, recognizing interference behaviors of the patient in real time based on the collected behavior environment data, and quantifying the interference behaviors to obtain influence data; and S3, based on the influence data, carrying out dynamic correction on the original and uninjured side temperature difference value to obtain a corrected and uninjured side temperature difference value, and carrying out dynamic correction on the tissue oxygen saturation to obtain the corrected tissue oxygen saturation. Through multi-source data fusion and intelligent correction, interference of patient behaviors and environmental factors on monitoring data can be effectively recognized and filtered out.
