Abstract:

During general anaesthesia different patient parameters are to be kept close to predefined targets. The objective of this study was to regulate the end-tidal CO2 concentration by means of an automatic control system that is based on a mathematical model, which is sufficiently descriptive for control purposes. The controller was designed to regulate the end-tidal CO2 concentration by adapting the ventilation parameters. A special algorithm adapts either respiration frequency (fR) and/or tidal volume (Vt), depending on the needs of the patient and which takes operator knowledge, peak airway pressure and requested minute volume into account. This new approach provides better performance as well as higher fault tolerance than in earlier studies with a fuzzy based controller.
