The main treatments for respiratory failure include: maintaining the usual airway, oxygen therapy, increasing ventilation to improve carbon dioxide retention, etiologic treatment, general supportive therapy, and monitoring and support of other important organ functions. 1. Maintaining the usual airway, such as removing secretions from the mouth, sputum suction may be needed for those with a lot of sputum, or even tracheal intubation or tracheotomy. 2. Oxygen therapy, commonly used oxygen therapy methods include nasal cannula oxygen, mask oxygen, etc. 3. Increase ventilation and improve carbon dioxide retention, such as using respiratory stimulants, mechanical ventilation, etc. 4. Treatment of the cause of the disease, such as respiratory failure caused by bacterial pneumonia, which needs to be treated with antibiotics such as moxifloxacin. 5. General supportive care, such as fluid management, prevention and treatment of electrolyte disorders and acid-base imbalance. 6. Monitoring and support of other important organ functions, for example, if renal insufficiency is caused, bedside hemofiltration and other treatments may be needed. In summary, respiratory failure requires prompt medical attention and standardized treatment, and severe cases need to be treated in ICU.
