Table 3.
The overall water loss (mL/min) of the three subjects with three minute ventilations
| Minute Ventilation | Subject | (a) 1D CT-based central airways |
(b) 3D CT-based central airways |
(c) 3D upper airways |
(d) 1D VF airways |
(e) Total water loss based on (a)+(c)+(d) |
(f) Total water loss based on (b)+(c)+(d) |
[(e)–(f)]/(e): 1D vs. 3D CT-based models (%) |
