WebDynamic 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.

Dynamic hyperinflation can occur in patients with asthma who are breathing spontaneously. It is a physiologic response to airflow obstruction and exists, to an extent, because increasing lung volume tends to increase airway caliber and can reduce the resistive work of breathing. However, in patients with severe asthma it becomes maladaptive, occurring at the expense of increased mechanical load and elastic work of breathing.
