[Systematic approach to transfusiology].

Possible methods of systemic approach to transfusiology as an independent science have been considered. It has been noted that, despite a great interrelation with other branches of science, transfusiology has its theoretical basis, and therefore the methods of other sciences, when used for transfusiologic purposes, acquire a definite tendency and specificity. As an example, the authors describe the main features of the systemic approach to controlling blood and circulation with the aim of selecting optimal tactics and strategy.
