[QUOTE=SagarNaik;23556]Forced Expiratory Time (FET) and Forced Expiratory Volume (FEV) are two different things.


Forced Expiratory Time (FET):[/B]

The time taken to expire a given volume during measurement of forced vital capacity.


Hello all,

Just wanted to clarify that F.E.T also stands for Forced Expiratory Technique, commonly called a 'huff'. It is performed at differing lung volumes, depending on where your are wanting to mobiles secretions from i.e more proximal or distal lung regions. I believe this is what the original question referred to. There has been a current post which has discussed this so looking at that may be helpful.
