Evidence from patients in the intensive care department of a multifield hospital treated for COVID-19 associated pneumonia with or without the use of a heated heliox mixture points to the beneficial effect of the mixture in the complex therapy of the disease. Comparative analysis of the clinical symptoms and laboratory data of the patients who received the heliox therapy and who did not (controls) testifies that heliox improves blood oxygenation, returns acid-base balance to normal, maintains dynamics of key pamaters positive and, therefore, increases effectiveness and shortens time of treatment.

The structure of traumatism and damages in 441 victims of river shipwrecks in 1983-2012 has been studied. The main types of damages in 172 rescuees in the river shipwrecks were light supercoolings (65.1 %), isolated, multiple and concomitant mechanical traumas (23.8 %), combined mechanical-cold traumas (7.6 %), combined mechanical-burn damages (3.5 %). Among 269 victims, the reasons of the lethal outcomes were drowning (68.4 %), mechanical damages (17.1 %), combined mechanical-cold traumas (10.4 %), combined mechanical-burn traumas (4.1 %). In the structure of the mechanical damages, combined two-factor mechanical-cold and mechanical-burn traumas among the rescued persons, there dominated light mechanical traumas and light cold traumas (29.3 %), and serious mechanical traumas (23.1 %) dominated among the victims.

New coronavirus infection is accompanied by high mortality and socio-economic losses in the world community. Despite the continuous process of including new medication with antiviral and anti-inflammatory effects in the disease treatment, the development of complications, primarily of hypoxic origin, and mortality remain high.The aim of the study is to evaluate the effect of the use of thermal oxygen-helium mixture in the therapy on the rate of regression of clinical and laboratory signs of inflammation, as well as the length of patient hospital stay.Material and methods. 59 patient medical records with moderate and severe disease were analyzed. The article summarizes experience of patient management with COVID-19-associated pneumonia who are treated with or without the use of thermal oxygen-helium mixture in one of intensive care units in multi-filed hospital.Results and discussion. It has been proven that the use of a thermal oxygen-helium mixture in the SARS-CoV-2 pneumonia treatment is effective.
