Acute respiratory distress syndrome (ARDS)
This is a characteristic appearance of ARDS in the appropriate clinical context.
The differential diagnosis includes infection (also a common complication of ARDS), and cardiogenic pulmonary edema. Differentiation can be impossible in some cases.
The causes of ARDS include:
- hypovolemic shock
- fat embolism
- viral pneumonia
- oxygen toxicity
- disseminated intravascular coagulopathy
ARDS mortality is high, around 50%, and many survivors develop chronic lung disease, with damaged lung healing by fibrosis. A minority recover fully.
