Study protocol for the lung model.

<p>Functional residual capacity (FRC), tidal volume (V_T), and respiratory rate (RR) generated in triplets are displayed as ranges. Respective dead space reducers (DSR 1–3) were applied to reduce post-capillary dead space to 1.5 mL, 16 mL, and 26.9 mL, respectively. Mean (range) intra-test coefficient of variation (CV) of generated nominal FRCs was 0.1 (0.0–1.8)%.
