Abstract
End-tidal steady state diffusing capacity (DLCOss2) was measured with different ventilation rates at rest in healthy subjects and patients with pulmonary diseases. The results in the patients were compared with the Filley method (DLCOss1) during exercise. The DLCOss2 values in the patients at rest during normoventilation correlated better to exercise DLCOss1 than the DLCOss2 values obtained during hyperventilation. The reproducibility of DLCOss2 at rest with ‘standardized’ ventilation was comparable to that reported for exercise DLCOss1. The healthy subjects had low DLCOss2 values at rest when breathing quietly, but if correction for ventilation was made, they could be separated from those with pulmonary diseases.
