Treatment is best determined by the specific diagnosis. Unfortunately, a specific etiology often is not determined. General supportive measures include the following:

  • Smoking cessation should be counseled.

  • Good pulmonary hygiene is important.

  • Supplemental oxygen therapy may be useful for any patients who demonstrate significant hypoxemia (oxygen saturation [SaO2] less than or equal to 88% or PaO2< 55 mm Hg while breathing room air either at rest or upon exertion).

  • If inhalational exposures are thought to be the etiology, as in HP and occupational forms of interstitial lung disease, removal from exposure is mandatory.

  • If a toxic medication is suspected, its discontinuation is mandated.

  • Respiratory infections should be promptly treated.

  • Pulmonary rehabilitation may improve exercise tolerance and quality of life.
