The article discusses the pathophysiology of hypoxia, the mechanisms of its elimination with oxygen therapy, and the toxic effects of oxygen. It also highlights modern recommendations and algorithms for application in cardiovascular diseases, including in combination with bronchopulmonary pathology. Given the data of evidence-based medicine, controversial and unclear aspects of oxygen therapy and the possibility of negative consequences if used incorrectly are discussed. The world experience of using oxygen therapy for the new COVID-19, including additional methods for improving the oxygenation (prone position), is discussed, and the author also shares his personal experience in treating comorbid patients with COVID-19. The modern methods of inhalation oxygen therapy and indications for their use, including non-invasive ventilation, high-flow nasal oxygenation (a promising, but no t widely used technique in our country), various types of oxygen therapy with masks, devices for home oxygen therapy are described.

Keywords: oxygen therapy, hypoxemia, oxygen, blood oxygen saturation, saturation, acute respiratory distress syndrome, new coronavirus infection, COVID-19, inhalations, oxygen masks.
