[The use of a mathematical method in evaluating the severity of the condition of patients with pyopneumothorax]. / Ispol'zovanie matematicheskogo metoda v otsenke tiazhesti sostoianiia bol'nykh s piopnevmotoraksom.

The course of pyopneumothorax in 427 patients, among whom 310 were subjected to temporary occlusion of the bronchus, was appraised by means of the severity index based on consideration of deviations of the values of hemodynamics, external respiration, blood, and acid-base equilibrium from the normal level. In a favourable course of pyopneumothorax the severity index was found to be within the ranges of the confidential interval. The method makes it possible to appraise the compensatory properties of the organism and prognosticate the course of the disease.
