 In 1994, the American–European Consensus Conference provided a revised definition of ARDS that designated patients with a ratio of partial pressure of arterial oxygen to fraction of inspired oxygen (PaO2/FiO2) of 300 mm Hg or less as having acute lung injury, and reserved the term ARDS for patients with more severe hypoxaemia (PaO2/FiO2 ≤200 mm Hg)

 In 2012, the Berlin definition of ARDS recommended that the term be expanded to include patients with an initial PaO2/FiO2 of 201–300 mm Hg who were receiving invasive or non-invasive ventilation with a tight-fitting mask and PEEP or continuous positive airway pressure (CPAP) of at least 5 cm H2O; this group was designated as having mild ARDS. PaO2/FiO2 of 101–200 mm Hg defined moderate ARDS and PaO2/FiO2 of 100 mm Hg or less was termed severe ARDS

一、時間

  • 急性發作，在已知臨床危險事件後一週內發生（如肺炎、敗血症、創傷等）

? 二、胸部影像

  • 雙側肺浸潤陰影，無法完全用心臟衰竭或液體負荷過多來解釋

? 三、氧合異常：以 PaO₂/FiO₂ 比值分類嚴重度

分類 PaO₂/FiO₂（mmHg） PEEP 要求（或 CPAP）
輕度（Mild） ＜300 PEEP ≥ 5 cm H₂O
中度（Moderate） ＜200 PEEP ≥ 5 cm H₂O
重度（Severe） ＜100 PEEP ≥ 5 cm H₂O
ㅤㅤ

? PaO₂：動脈血氧分壓
? FiO₂：吸入氧濃度（fraction of inspired oxygen）

? 四、病因不能用心因性肺水腫來解釋（例如評估心臟超音波以排除心衰

<300即為輕度ARDS
