Lung Diffusing Capacity for Carbon Monoxide in Coal Miners with Pneumoconiosis

The scanned text of this document is badly garbled. The library citation labels it 'Enclosure 8 - Lung Diffusing Capacity for Carbon Monoxide'. The garbled title printed on the document itself appears to be longer and also seems to name an alveolar-arterial measurement. Its reference list cites lung physiology papers on carbon monoxide diffusing capacity and on the oxygen difference between the lung's air sacs and arterial blood. Fragments point to authors at Belgian institutions, apparently including a university in Louvain. They also point to work on pneumoconiosis, the dust disease of the lungs found in miners, among men working underground in a coalfield. One fragment appears to refer to an earlier investigation of 381 volunteers, and another to a newer study meant to confirm and complete it. No legible passage mentions asbestos. The exact numbers of people in the newer study and its numerical results cannot be read reliably. Readers who need this document should consult a clean copy.

We wrote this plain-English summary from the full article with the help of AI, and a second AI model checked each sentence against the article. It is not the authors' wording; the abstract and the article are their own account.

From J-M's medical library

This copy comes from the Johns-Manville medical library. It was among the papers J-M kept in its medical library without an index entry.

We publish this piece for research and commentary: it shows what the medical literature in a leading asbestos company's own library said on the subject, and when. Our summary above is our own reading of it. The copyright stays with the publisher.
