Which of the following volume is expired in forced expiration???
wht exactly do u mean by forced expiration?
-for FEV it will be vital capacity
-howver after tidal expration it will be fuctional residual capacity!
Forced expiration or max: expiration.......Vital capacity..
You r rite.... 8)
SDK -I always thought the answer to this was expiratory reserve vol.
As far as I know the RV is left but cant be measured by spirometry.
RV +ERV =FRC
