Method for recognizing and identifying emergency situations in an anesthesia system by means of a self-organizing map
First Claim
1. A method for recognizing and identifying emergency situations in an anesthesia system comprising:
- a) measuring a plurality of variables associated with an anesthesia delivery to produce measurement values associated therewith,b) forming the measurement values of said measured variables into pattern vectors characterizing instantaneous states of the system,c) providing a emergency identifying self organizing map;
d) training the emergency identifying self organizing map, prior to an actual measurement situation, by providing reference material comprising pattern vectors corresponding to actual situations, the pattern vectors being arranged in said self organizing map as weight vectors, each weight vector representing a particular combination of system parameters representing an actual condition, ande) comparing the pattern vectors formed from the measurement results with weight vectors (m1) of the emergency identifying self-organizing map to recognize and identify emergency situations.

Abstract
A method for recognizing and identifying emergency situations in an anesthesia system measures a plurality of variables associated with an anesthesia delivery, the measurement values of said measured variables are formed into pattern vectors characterizing the instantaneous states of the system, the system is trained prior to the actual measurement situation with a reference material comprising pattern vectors corresponding to actual situations, and on the basis of measured pattern vectors corresponding to actual situations, and on the basis of measured pattern vectors and trained material, the emergency situations are recognized and possibly identified. The reference material is trained to the system using self-organizing maps, and the pattern vectors formed from the measurement results are compared with weight vectors (m1) of the self-organizing map to recognize and identify the emergency situations.
