Overview
According to the 2012 Berlin Definition, ARDS is classified according to severity as mild, moderate, or severe. These levels of severity are based on the degree to which oxygenation relative to the amount of supplemental oxygen being delivered to the patient via positive pressure ventilation.
Classification
The current ARDS diagnostic criteria (commonly referred to as the Berlin Criteria or Berlin Definition) were established by the ARDS Definition Task Force in 2012. The Berlin Definition classifies ARDS as mild, moderate, and severe based on the degree of oxygenation impairment relative to the concentration of inspired oxygen being delivered to the patient via positive pressure ventilation. These three levels of severity serve as a means of risk-stratifying patients, as each level is associated with a mortality risk based on pooled data from a large patient population with ARDS.[1]
The ARDS diagnostic criteria and risk stratification are discussed in greater detail in the subchapter on the diagnostic criteria for ARDS.
