PseudoARDS-Collapse pattern PseudoARDS-collapse is respiratory failure which is largely due to atelectasis. The most common form of this is collapse of the lower lobe(s) or dependent lung tissue, which is a common problem among morbidly obese patients or intubated patients (and especially morbidly obese patients who are intubated). #Diagnosis #Clinical #CXR #ChestXRay #PseudoARDS #Atelectasis #Collapse #Pattern
