1. Asthma : FEV1 sec decrease, FVC decrease, so FEV1 sec/ FVC see decrease,
TLC : decreases? not sure abt this, FRC : increase, RV : increase.
2. CF pt: i think everything would be decrease here.
3. atlectasis : FEV1 sec : decrease, FVC : decrease, FEV1 sec/ FVC : increase ?

well dabears i'll try to help. If u have an obstructive disease like asthma, these will increase: TLC (total lung capacity), RV ( residual volume) and FRC (functional residual capacity) now since it's an obstructive disease u will be able to inspire a lot of air (IRV) but to expire it quickly in one second is not possible (because of the obstruction).
