Anaesthesiology is practiced within a complex socio-technical system that can reach an infinite number of states. Therefore, traditional methods of requirements engineering are not suited to model the tasks and support requirements of the anaesthetist. We introduce an approach for developing decision support systems in anaesthesiology based on a model of situation awareness and its determinants during surgery. This model is combined with a cognitive process model of anaesthetists' decision making to identify situations where decision support is most useful. We demonstrate that these situations can be identified on the basis of measurable patient state variables and introduce a preliminary knowledge-based system for decision support.
