FUSILLO, José et al. Adjustment of reference Equations to Carbon Monoxide Diffusion Tests (DLCO) in reports from a laboratory in Asunción city. Rev. cient. cienc. salud [online]. 2025, vol.7, e7110.  Epub May 22, 2025. ISSN 2664-2891.  https://doi.org/10.53732/rccsalud/2025.e7110.

Introduction. The diffusion test for carbon monoxide (DLCO) constitutes an important adjunct in the arsenal of resources for pulmonary function studies. Objective. To compare the performance of DLCO predicted values proposed by four equations. Material and Methods. Qualitatively acceptable reports of DLCO tests from a pulmonary function laboratory in Asuncion, Paraguay were analyzed by means of an observational study. The adequacy to the predictions proposed by Miller, Knudson, Paoletti and the Global Lung Initiative (GLI) was studied. Results. In both sexes, the GLI reference parameters were better adjusted to the values measured in this sample. Conclusion. It is relevant to have a single language for the expected values when measuring pulmonary function variables in order to homogenize key aspects of the diagnosis and management of certain respiratory diseases.

Keywords : respiratory function tests; pulmonary diffusing capacity; reference values.
