Acute hypersensitivity pneumonitis tends to occur 4-12 hours after exposure (usually heavy exposure) to the particles. Lung function tests that examine the lung volumes and the ability for gases to move through the lungs (diffusing capacity) are then performed. After a while, the inflammation stops. It represents a collaborative effort among the American Thoracic Society, Japanese Respiratory Society, and Asociación Latinoamericana del Tórax. Shortness of breath, cough, and vascular problems are symptoms caused by interstitial lung disease, and their treatment depends on the underlying cause of the tissue thickening.
