Sources of error in partial rebreathing pulmonary blood flow measurements in lungs with emphysema and pulmonary embolism

Studies of the accuracy of partial rebreathing measurements of pulmonary blood flow (PBF) in patients with abnormal lungs have not fully explained the sources of error. We used computer models of emphysema and pulmonary embolism incorporating both ventilation-perfusion ( V˙/ Q˙) and ventilation-volu...
