Simultaneous Measurement of Pulmonary Diffusing Capacity for CO and Cardiac Output by a Rebreathing Method in Patients with Pulmonary Diseases

Pulmonary diffusing capacity for CO (DLCO) and cardiac output (Q) were simultaneously measured by a noninvasive rebreathing method (RB) in 15 normal subjects and in 60 patients, including cardiac diseases (CD), bronchial asthma (BA), chronic obstructive pulmonary disease (COPD) and idiopathic pulmon...

Zusammenfassung:	Pulmonary diffusing capacity for CO (DLCO) and cardiac output (Q) were simultaneously measured by a noninvasive rebreathing method (RB) in 15 normal subjects and in 60 patients, including cardiac diseases (CD), bronchial asthma (BA), chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (PF). DLCO and Q were tested by the single breath method (SB) and the dye-dilution method (Dye), respectively. DLCO(RB) correlated well with DLCO (SB) (r=0.890, p
