A fuzzy sets theory application in determining the severity of respiratory failure.

This paper proposes to apply the theory of fuzzy sets in determining the severity of respiratory distress of a patient in an intensive care unit. The problem is modelled as a fuzzy multicriteria decision-making one. Theoretical approaches to the situation are considered. The proposed fuzzy selection method, based on the usage of the fuzzy intervals, is described. An example of determining the severity of respiratory distress is used to illustrate the presentation. Computer implementation of the model is considered, and the directions for possible further work are pointed out.
