An autonomic nervous system is screened by adopting an autonomic nervous system dysfunction risk screening model, and the vertical and horizontal systolic pressure, diastolic pressure and heart rate, the systolic pressure, diastolic pressure and heart rate induced by continuous force, the heart rate induced by deep breath, the systolic pressure, diastolic pressure and heart rate of a patient under the mental calculation condition, the blood pressure of the patient under the Valsalva action condition, the systolic pressure, diastolic pressure and heart rate of the patient under the ice bag induction condition, the systolic pressure, diastolic pressure and heart rate of the patient under the hyperventilation condition and the systolic pressure, diastolic pressure, blood pressure and heart rate of the patient under the long-range upright tilt condition are substituted into the autonomic nervous system dysfunction risk screening model. The autonomic nervous system dysfunction risk screening model is used for comprehensive evaluation, an autonomic nervous system screening evaluation result is given, the accuracy of autonomic nervous system dysfunction judgment is improved, and a tool is provided for medical staff to judge autonomic nervous system dysfunction of a patient.
