Acute respiratory distress syndrome and respiratory failure are the main life-threatening conditions in patients with COVID-19. The main reason is, first of all, impaired lung perfusion. Non-invasive ventilation of the lungs can eliminate hypoxemia and reduce inspiratory efforts. The use of mechanical ventilation to prevent self-induced lung injury (P-SILI) is considered as an optimization option. The leading characteristic of the progression of COVID-19 is the gradual transition from edema or atelectasis to less reversible structural changes in the lungs, namely fibrosis. As a result, the mechanics of breathing is disturbed, PCO2 in the arterial blood rises, the work of the respiratory muscles decreases, and there is no response to positive pressure at the end of exhalation in the prone position.
