WebIt’s called dynamic hyperinflation. Overextension can cause your lungs to be less flexible even when you’re at rest, or not doing anything. That’s called static hyperinflation. 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.
