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. WebMar 9, 2024 · There was a strong association between dynamic hyperinflation measured by CPET and MPT (rho 0.660, p < 0.001), and a moderate association between CPET and the 6-MWT (rho 0.361, p 0.024). Measurements of dynamic hyperinflation with CPET and MPT were plotted in a Bland–Altman plot (Fig. 1). There was a mean difference of 202 …

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.
