The CO single breath transfer factor of the lung. A reliable clinical parameter in valvular heart disease.
The CO single breath transfer factor of the lung expressed per unit of alveolar gas volume during breath-holding, Tv, and its component factors Dmv and Vcv have been determined in 46 patients suffering from valvular heart disease. It has been shown that Tv cannot be correctly interpreted, unless the values of Dmv and Vcv are known. The results of measurements of gas transfer using this method offer a reliable guide for establishing the efficacy of the cardiac pump, and for following up the effect of therapy in valvular heart disease.
