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. These levels also serve as a means of risk-stratifying patients, as each level is associated with a different mortality risk based on pooled data from a large patient population with ARDS.[1]
