Alternative Names for ARDS
Acute Respiratory Distress Syndrome (ARDS) has historically been called by several other names, most notably "shock lung," "traumatic wet lung," and "congestive atelectasis" 1.
Historical Nomenclature
The syndrome we now recognize as ARDS was described in its modern form in 1967, but the clinical entity had been observed for decades prior under different names 1. These historical terms reflected the understanding of the syndrome at the time:
- Shock lung - emphasizing the association with shock states
- Traumatic wet lung - highlighting the trauma-related etiology and pulmonary edema
- Congestive atelectasis - describing the radiographic and pathophysiologic appearance
Current Terminology
Today, the universally accepted term is Acute Respiratory Distress Syndrome (ARDS), which has been standardized through multiple consensus definitions including the 2012 Berlin definition and the 2024 American Thoracic Society guidelines 2, 3. The syndrome is now classified by severity (mild, moderate, severe) based on PaO2/FiO2 ratios rather than by alternative names 2, 3.
The term "ARDS" should be used in all contemporary clinical documentation and communication, as the historical names are outdated and no longer reflect our current understanding of the syndrome as an acute inflammatory process resulting in diffuse lung injury with non-cardiogenic pulmonary edema 1, 4.
