The priority value of monitoring in the process of postoperative (as well as intraoperative) intensive therapy is determined not only by the dynamism and polyfunctionality of the changes occurring in the body, but also by the modern possibilities of probabilistic modeling of the evolution of pathophysiological processes and prediction of complications. The latter condition is necessary for the implementation of the most important principle of intensive therapy — its prophylactic orientation.

Technological progress has led to the creation of numerous intensive observation systems that differ in the nature of the effect on the patient’s body, the type of controlled function, the essence of the physicochemical effects lying in the pine system, the speed of obtaining information, the degree of its processing, the nature of the response to physiological and pathological deviations of the measured parameters of vital activity, the ability to eliminate these deviations, the number of simultaneously recorded parameters and patients served. The degree of complexity and the amount of monitoring depend on the severity of the patient’s condition, the nature of the pathology and the capacity of the medical institution.In the clinic of thoracic surgery of the Military Medical Academy, this possibility was realized in the process of developing and using the Consilium MT information system of operative medical monitoring (ISOVK). The system provides continuous removal of biomedical information in the required volume, its automatic processing, measurement and calculation parameters that allow assessing the state of vital organs and body systems, integral assessment of the state of the whole organism, signals the occurrence of hazardous conditions, automatically detects the transition of parameter values ​​of predetermined thresholds, visually displaying and documenting the results of the control.

Sources of information in the complex are: -electrocardiogram in any “chest” lead, providing

satisfactory cardio signal; – integral rheogram of the body according to M.I. Tishchenko (ITGT); – pneumogram, which is a function of the patient’s perimeter chest changes

breathing process; -internal (rectal) and surface (on the rear foot) temperature; – diuresis during catheterization of the urethra of the patient.

As a result of automatic information processing, the following parameters are measured and calculated and continuously displayed on the video monitor screen:

– heart rate, heart rate dispersion, the presence of arrhythmia; – basic resistance, shock index, coefficient of respiratory changes in the stroke volume of the left ventricle, the integral tonicity factor of blood vessels, the coefficient of blood circulation reserve and the balance indicator

extracellular fluid (according to IRGT); -the frequency of respiration and the ratio of the phases of the respiratory cycle; -internal and surface temperatures, as well as the difference between them; – diuresis rate and amount of excreted urine.

The complex is used for pre-, intra- and postoperative medical monitoring and in combination with other monitoring methods (pulse oximetry, capnometry, determination of oxygen and carbon dioxide tension by the percutaneous method), providing the possibility of not only an integrated assessment of the patient’s condition, system functioning stress , their interaction and mutual compensation, but also the timely identification of the leading causes of pathological changes.

In the postoperative period, hypoxia most often plays the role of such a key mechanism of pathogenesis, which, together with the primary damaging factors (illness, surgery, anesthesia, etc.), makes adaptive reactions pathological, contributes to the formation of energy-structural deficiency and the emergence of a real threat of irreversible decompensation of vital functions . The ability to prevent hypoxia and ensure compliance of oxygen transport at its various stages with tissue needs and determines the place and importance of each therapeutic measure in the general system of intensive care.
