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 … See more 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 … See more Interventions to correct air-trapping include decreasing the respiratory rate (increasing expiratory time), increasing inspiratory flow rates (decreasing the inspiratory time) and lowering the tidal volume. Adults In adults, it has … See more irts centredoc

WebFIGURE 2. Pressure (P)–volume (V) relationships of the total respiratory system a) in normal and b) in chronic obstructive pulmonary disease (COPD).Tidal P–V curves during rest ( ) and exercise ( ) are shown. In COPD, because of resting and dynamic hyperinflation (a further increased end-expiratory lung volume (EELV)), exercise tidal … WebSep 7, 2015 · Dynamic hyperinflation (DH) refers to the variable increase in end-expiratory lung volume (EELV) above the relaxation volume (VR) of the respiratory … WebAug 22, 2005 · Dynamic hyperinflation is more common and can occur independent of or in addition to static hyperinflation. It results from air being trapped within the lungs after each breath due to a disequilibrium between the volumes inhaled and exhaled. The ability to fully exhale depends on the degree of airflow limitation and the time available for ... irts bourges
