Suggest update to label in PhenX (from "Lung Function - Lung Volume") Perhaps use the protocol source in PhenX to include different ways of measuring FRC (functional residual capacity) as subclasses (e.g. Measurement of FRC using body plethysmography, Measurement of FRC using nitrogen washout, Measurement of FRC using helium dilution, Measurement of lung volume using imaging techniques).
