Comparative Study
Comparison of four different display designs of a novel anaesthetic monitoring system, the 'integrated monitor of anaesthesia (IMA)'.
A novel monitoring system (integrated monitor of anaesthesia, IMA) which integrates three components of general anaesthesia on one single display was developed. The focus of this study was to evaluate the performance and user-friendliness of four different display designs. ⋯ A mixed numerical-graphical display design appears to present the best results in terms of user reaction times, response accuracy, and performance index when detecting abnormal critical events.
