Overview

Approximately 3 in 5 patients with chemical pneumonitis have clinical improvement with clearing of chest X ray. Approximately 1 in every 3rd patient shows a rapid improvement followed with a new progressive infiltrate that suggests a secondary superimposed bacterial infection or the development of ARDS. The least common course, but the one with the worst prognosis, is the development of fulminant disease resulting in acute death.
