Dynamic hyperinflation 日本語
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. 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. Dynamic hyperinflation can cause alveolar overd…
