Hi Watts,

I made two pulmonary function report (PFR) in 2004 and 2007, but the results are quite the same, even so i had increase my depths in 20m (from 30 to 50).

But I think that with specific tranning we might reduce RV a lot (needs research).

And yes TLC (total lung capacity) = RV + VC IN + Packing (but during my test they don't allow packing, only a continuous full inhale)

VC IN - vital capacity or full inhale (continuous)
RV - residual volume
ITGV - intrathoracic gas volume (maybe equal to FRC?)
TLC - total lung capacity
