[The principles of constructing a data bank applicable to the problem of physiological standards in space medicine]

The norm is a more complex problem in physiology and in space medicine in particular. Definition of norm and health concepts is analyzed. Classification of functional states based on the adaptation and homeostasis concepts is proposed. Various approaches to determination of a norm are described. Three types of the norms which are of significance for space medicine, namely rest norm, reaction norm, adaptive norm are identified. The structure of data bank containing information on the standards is described. The central data bank structure is considered.
