Regression data for respiratory impedance in healthy young children
| Parameter | Equation | SEE | R2 | p Value |
|---|---|---|---|---|
| Rrs6, Rrs8, Rrs10, respiratory resistance at 6, 8 and 10 Hz; Xrs6, Xrs8, Xrs10, respiratory reactance at 6, 8 and 10 Hz; Rrs4–24, average Rrs between 4 and 24 Hz. | ||||
| Respiratory impedance data are expressed in hPa.s/l and Ht in cm. | ||||
| SEE is the standard error of the estimate. | ||||
