摘要

Acute respiratory distress syndrome (ARDS) is defined as an acute inflammatory syndrome leading to increased pulmonary capillary leakage and subsequent interstitial and alveolar pulmonary edema. Hypoxia is the predominant symptom. The definition of ARDS comprises acute onset, bilateral patchy infiltration on chest X‑ray and a reduction of the ratio of arterial partial pressure of oxygen (PaO2) to the fraction of inspired oxygen (FiO2), which also determines the classification into mild (≤ 300), moderate (≤ 200) and severe (≤ 100) ARDS. Treating the underlying cause is the only causal treatment measure. The aim of adjunctive therapy is the maintenance of life or organ functions by ensuring an adequate gas exchange without further damaging the lungs. Adjunctive therapy consists mainly of individually adapted “protective” ventilation treatment and the prone position. In severest ARDS, the use of venovenous extracorporeal membrane oxygenation (VV-ECMO) can improve survival if strict criteria for indications and contraindications are followed.
