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.

WebNov 16, 2014 · Based on the results we’ve seen in several studies we’ve decided that a decrease in IC of 0.25 L or greater is a significant change and an indication that hyperinflation is probably occurring. We use the Vt/IC ratio to help determine whether hyperinflation, when it occurs, may be causing a ventilatory limitation. 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.
