Table 4.
Coefficients of repeatability (CR) retested after one hour (n = 237), after five hours (n = 79) and after 3-10 days (n-76) (in % from initial value/absolute value)
| Parameter | Retest after one hour | Retest after five hours | Retest another day |
|---|---|---|---|
| FEV1 | 11.8 | 13.7 | 17.9 |
| IC | 18.9 | 21.3 | 22.7 |
| FIV1 | 13.5 | 17.9 | 18.0 |
| PIF | 17.9 | 17.8/0.90 | 17.9/0.85 |
| MIF50 | 20.4 | 21.0 | 19.2 |
FEV1 = Forced Expiratory Flow in one second; FIV1 = Forced Inspiratory Flow in One second; IC- Inspiratory Capacity; MIF50 = Maximal Inspiratory Flow at 50%; PIF = peak Inspiratory Flow.
