Q: All of the following are recommended to pursue during acute exacerbation of Idiopathic Pulmonary Fibrosis (AE-IPF) except?

A)  High-flow oxygen

B) Anti-acid/reflux treatment
C) Invasive mechanical ventilation
D) Broad spectrum antibiotic 
E) High dose steroids


Answer: C

 Invasive mechanial ventilation has an extremely high mortality in acute execerbation of IPF, and should be pursue only if patient or family insist despite full discussion and disclosure of potential harm, and high probaility of its failure as a salvage therapy..

Choice B may look surprising but reflux has been described as a possible cause of AE-IPF.
