The difference in results between two lung diffusion study systems

The single-breath diffusing capacity of the lungs for carbon monoxide test (DLCO-SB test}, also known as the transfer test, is a pulmonary function test which is in common use in the respiratory laboratories of hospitals and medical practices. It gives a measurement of the efficiency of the transfer of gases between the pulmonary capillary blood and the alveolar lung spaces. This chapter provides information on diffusion in the lungs, modelling diffusion, and basic information about single breath diffusion studies. The problem investigated in this study, the significance of the study, and a brief review of previous closely related research, is presented. The chapters following, present the experimental approach adopted for investigating the problem, and a presentation and discussion of the findings
