1. A system for monitoring a patient and controlling patient treatment, the system comprising:

  • a patient sensor for capturing a patient signal;

    a user interface for providing a user with information on the captured patient signal;

    an integrated closed loop controller which is fed with the patient signal in a processed state and which controls a patient treating device for treating the patient, wherein the integrated closed loop controller includes a transfer function model controlling the patient treating device based on an input target value for the patient signal, wherein the transfer function model is dynamical adjusted based on deviations between the input target value and an output value of the patient signal, and wherein the user is provided with a warning in response to dynamic adjustment of the transfer function model;

    a monitoring processer for processing the patient signal and for outputting processed data to the user interface; and

    a control processer for processing the patient signal and for outputting the patient signal in the processed state to the integrated closed loop controller, wherein the monitoring processer and the control processer are fed with the same patient signal in the same pre-processing state.
