Automatic control methods in medicine

As an introduction, a comparison between biological and technical control systems is presented. It is emphasized that most physiological systems are somehow feedback controlled, but are often difficult to model accurately. Subsequently, the human respiratory system is introduced. It is explained why this system serves well as a possible example of modern control and diagnosis applications. A scheme for automated diagnostic support in lung function analysis of spontaneously breathing infants is presented. It is demonstrated that to improve diagnostic support, it is more important to extract knowledge from data in an optimal manner than to optimize the subsequent pattern classification algorithm. After this, a novel method to identify and control this system in artificially ventilated patients with adult respiratory distress syndrome (ARDS) is discussed. A summary and some concluding remarks are given.
