Dynamic hyperinflation is a phenomenon that occurs when a new breath begins before the lung has reached the static equilibrium volume. In simpler terms, this means that a new breath starts before the usual amount of air has been breathed out, leading to a build-up of air in the lungs, and causing breathing in and out to take place when the lung is nearly full.
