Overview
According to the Berlin Definition, ARDS may be classified by the severity of oxygenation deficit into three subtypes: mild, moderate, and severe.
Classification
ARDS may be classified according to the Berlin Definition into three mutually exclusive subtypes: mild, moderate, and severe. These levels of severity are based on the PF ratio, the degree of oxygenation relative to the fraction of oxygen participating in gas exchange. Data from the pooled cohorts demonstrated that mild, moderate, and severe ARDS were associated with increased mortality (27%, 32%, and 45%, respectively) and increased median duration of mechanical ventilation among survivors (5 days, 7 days, and 9 days, respectively).[1]
