FRC
These definitions apply to FRC:
mean value: FRC, IC, ERV, VT, IRV , LCI, CEV, VT, M0, MR1, MR2
Get largest VC from FRC maneuver
RV[reported] = FRC[average] - ERV[average]
TLC[reported] = RV[reported] + VC[largest] = FRC[average] - ERV[average] +
VC[largest]

Moment Value and Moment Ratios
1 and 2 from nitrogen washout
moment analysis. Clinical use of
these parameters is limited since
the available reference data is
based on a small number of pati-
ents (see "Literature" on page 182
[17] to [21]); for a detailed descrip-
tion, please refer to chapter "Easy-
One Pro LAB Washout Moment
Analysis" on page 180 in the
Appendix of this manual.
