This reduces the amount of air that can pass through and in the end can lead to wheezing sound. Asthma is furthur classified according to frequency of symptoms, it also results in forced expiratory and sometimes into peak expiratory flow rate. Asthma might also be classified into extrinsic or intrinsic which is based on the symptoms which are precipitated by the allergens.
