Özet:

With acute respiratory failure and hemodynamic instability, dyspnoe and breathing difficulties, breathing number ≥28 / minute, 5 liters / minute and above, although nasal oxygen supports oxygen saturation <93, 5 liters / minute and above, while nasal oxygen supports part oxygen pressure <60 mmHg, PaO2/FiO2 <300 are Covid-19 pneumonia critical patients and should be treated and monitored in a intensive care unit. These patients should be thoroughly evaluated in the direction of clinical, laboratory and imaging findings after being accepted to intensive care. First of all, if the traditional oxygen support therapies (nasal canal, face mask, and reservoir mask) cannot get the result to be initiated, high-flow nasal canulation should be applied, and if this method fails, non-invasive mechanical ventilation should be initiated. Although the oxygen support therapy is carried out, if the target oxygen saturation, breathing number and optimal respiratory physiology are not achieved, in this case it is necessary to pass to the entubation and mechanical ventilation support therapy without losing time. When the patient is suitable, the standard weaning procedure should also be applied. In patients with Covid-19 pneumonia, mortality occurs at the ground of developing ARDS and with additional negative prognostic factors from 25 to 50%.
