[Hemodynamic aspects of the treatment of patients with "critical ischemia" of the lower extremities].

A complex examination of 60 patients with different stages of disturbances of blood circulation (by the Fontain classification) with chronic arterial insufficiency was performed. Specific features of regional hemodynamics were revealed in patient with "critical ischemia" (3rd and 4th stages of the disease). Threshold values of the "critical ischemia" were determined, most informative of them being the malleolus index and oxygen pressure on the foot. An analysis of results of the investigation in the dynamics of the treatment performed has shown possible effectiveness of restorative operations in treatment of patients with severe stages of chronic arterial insufficiency.

[Program for interpreting acid-base disorders and assessing blood oxygenation].

The paper describes a program for the interpretation of deviations in the acid-base state (AAS) and the estimation of the blood oxygenation levels. The program was developed for the Iskra-226 microcomputer and is intended for a direct measurement of the gas composition of the blood. The program makes it possible to calculate the AAS and the blood oxygenation levels (20 parameters), to estimate the AAS deviation type and the degree of its compensation, it accumulates and stores the patient data, keeps records of case histories.

[Educational programs on ventilation-perfusion ratio].

The paper describes a learning programme for calculating the characteristics of arterial blood from the ventilation-perfusion ratios in the lungs by using a three-variable mathematical model of the lung. The lungs are presented as a set of three components which differ in ventilation and perfusion: 1) a fraction of ventilated and O2-perfused alveoles; 2) a fraction of non-perfused and ventilated alveoles; 3) a fraction of unventilated and non-perfused alveoles. Results of calculations are provided.
