Cigarette smoking causes most lung cancers. The more cigarettes you smoke per day and the earlier you started smoking, the greater your risk of lung cancer. High levels of pollution, radiation and asbestos exposure may also increase risk. Lately researchers connect this lung cancer with genetic factors.

Fef 25 75 obstruction

Maximum expiratory flow when x% of the FVC has been exhaled (FEF x% ) or x% of the FVC remain to be exhaled (MEFx%, now deprecated) is assessed in either of three ways:

The reproducibility of forced expiratory flows diminishes in the cited order of recommendations in adults and adolescents. In practice the third recommendation (ATS) is most frequently used, but it cannot be applied in young children .

If the maneuver is performed properly, forced expiratory flows between 25% and 75% of the FVC are effort independent because they are determined by a flow limiting segment developing in intrathoracic airways. Effort independence has led to the misconception that forced expiratory flows would provide more reliable and more ‘sensitive’ indices of airway obstruction than for example the FEV 1 . The opposite is the case:
