From: Effect of nocturnal EPAP titration to abolish tidal expiratory flow limitation in COPD patients with chronic hypercapnia: a randomized, cross-over pilot study

Fig. 3

EPAP and tidal expiratory flow limitation index during the night with EFLT-abolishing-EPAP vs. fixed-EPAP. Data are reported as individual values (open symbols dotted lines) and as mean ± SD of all subjects (closed symbols). Dashed-line: tidal expiratory flow limitation threshold. EPAP: expiratory positive airway pressure. ΔXrs: difference between mean inspiratory and expiratory reactance (tidal expiratory flow limitation index). ΔXrs data for 11 subjects
