ARDS is mainly treated by Western medicine: 1, treatment of primary disease, currently it is believed that infection trauma or systemic inflammatory response syndrome is the root cause of ARDS, control of primary disease, containment of induced or systemic and uncontrolled inflammatory response is necessary to prevent and treat ARDS. 2, respiratory support therapy. Respiratory therapy measures are more: the first one is oxygen therapy. The second is non-invasive mechanical ventilation, which is often built on the basis of high-flow oxygen inability; the third is invasive mechanical ventilation, invasive mechanical ventilation requires attention, that is, the timing of mechanical ventilation, in general, should be early rather than late, because ARDS patients are relatively heavy, late words often This can lead to adverse events. Pulmonary protective ventilation, often referred to as small tidal dose, high PEEP positive end-expiratory pressure ventilation, the choice of PEEP includes spontaneous breathing, semi-recumbent position, sedation, analgesia and the application of hormonal drugs. The fourth one is liquid ventilation, which is also a treatment method because the patient himself is pulmonary edema. The fifth is the extracorporeal membrane oxygenation technique, which is the common use of ECMO.3. Drug therapy. The first one is the management of fluid, which is commonly used. The second is glucocorticoids, and alveolar surface active substances, including E cysteine, and acrylamide, etc. These drugs. There are also recombinant human activator protein, ketoconazole, fish oil, etc.; 4, Chinese medicine treatment: acupuncture point paste, Chinese frequency and moxibustion, and later is the Chinese medicine tablets and Chinese medicine rectal drip.
