Dynamic compression is when after inhaling a large volume of air you expire forcefully, after a short forceful expiration the flow of air through the airways become effort independent and more dependent of the radius of the airway because of a reflex compression of airways, leading to a decreased flow.
An example would be that of a diver, when he dives before jumping into the water he will take a large breath in and then do a sudden short forceful expiration so that the flow becomes effort independent and hence decreased due to dynamic compression leading him to "hold his breath" for a longer period of time.
