Abstract:
Methodically it is very simple to determine fractional CO-uptake (FCO) from inspiratory and mean expiratory CO-concentrations. In two longitudinal studies the single-breath-TCO (49 patients) and FCO (813 patients) have been compared. The oscillations of DCO are smaller than those of TCO, but it remains unclear which method for determination of CO-transfer has a higher validity.
