Abstract: A patient state monitoring system and a method for monitoring patient state are disclosed. The patient state monitoring system includes a monitoring device and a monitoring module communicationally connected to the monitoring device, the monitoring module being worn on the patient's body. The patient state monitoring system also includes a processor that obtains parameters, and sets the operating mode of a monitoring module according to the obtained parameters, where the operating mode of the monitoring module comprises a continuous monitoring module and an intermittent monitoring mode. By use of the patient state monitoring system and method, during the monitoring of a patient, strict monitoring of the user's physical condition can be satisfied and the processing of redundant data can be reduced, thereby improving monitoring efficiency and quality.
