Table 1. Baseline settings per patient group.
| Healthy (n = 10) | Preterm (n = 10) | CF (n = 10) | |
|---|---|---|---|
| Age (years) | 6.1 ± 0.1 [6.0–6.4] | 7.9 ± 0.8 [6.6–9.2] | 12.3 ± 3.6 [5.1–18.1] |
| Dead space reducer set | 2 | 3* | 3* |
| Individual delay times | |||
| O2 delay (ms) | 601 ± 4 (599–604) | 615 ± 8 (608–620) | 622 ± 5 (619–626) |
| CO2 delay (ms) | 51 ± 3 (49–53) | 58 ± 3 (56–60) | 62 ± 2 (61–64) |
| Averaged delay times for baseline | |||
| O2 delay (ms) | 601 | 618 | 618 |
| CO2 delay (ms) | 51 | 60 | 60 |
| Individual signal change | |||
| O2 delay (ms): ±20, 40, 60 ms | 581, 561, 541 and 621, 641, 661 | 598, 578, 558 and 638, 658, 678 | 598, 578, 558 and 638, 658, 678 |
| CO2 delay (ms): ±10 ms | 41 and 61 | 50 and 70 | 50 and 70 |
Data are given as mean ± SD, [range] and (95% CI). Baseline settings per patient group. Individual delay times per file, averaged delay times per dead space reducer set used as baseline, and individual changes for O2 and CO2 delay.
*For logistic reasons at the time of measurement in two children of the preterm group and two children of the CF group we had to use set 3 instead of 2.
