METHOD FOR DIAGNOSING PULMONARY DISEASES CAUSED BY WELDING AEROSOL Russian patent published in 2001 - IPC

FIELD: medicine. SUBSTANCE: method involves applying X-ray and clinical laboratory examination and determining partial oxygen pressure in patient blood. Lavage liquid is additionally examined for determining siderophage and alveolar macrophage quantity. Relation between the general siderophage and general alveolar macrophage quantities is interpreted as coefficient of lung iron dust contents. Partial oxygen pressure in blood being less than 80 mm of mercury column and coefficient of lung iron dust contents being greater than 0.5, lung disease caused by welding aerosol is to be diagnosed. EFFECT: high accuracy of early stage diagnosis method.
