Expiratory Flow Limitation Definition, Mechanisms, Methods, and Significance
Figure 3
Comparison of FEV1, IC, DLCO, and KCO in COPD patients who exhibit tidal expiratory flow limitation (EFL) in the supine position (FL; ) versus those who do not (NFL; ). Both DLCO and KCO are significantly lower in FL patients (*), suggesting that emphysematous patients are more prone to develop recumbent EFL.
