WebDec 1, 2011 · In our study, we had a further evidence of the effect of dynamic hyperinflation on left ventricle stroke volume. Indeed and most important, we found that DP reserve was inversely related to the dynamic hyperinflation during exercise. In addition, heavy hyperinflators had a high likelihood to have a DP reserve value ≤ 10,000 mmHg · … WebHyperinflation happens when the lungs lose some of their elasticity, or stretchiness. Since the lungs cannot stretch as well, it is hard to fully exhale. This traps the leftover air in the lungs. 1 When this happens during physical exercise, it is called dynamic hyperinflation. It can also happen when a person is at rest.

WebPatients with severe chronic obstructive pulmonary disease (COPD) develop dynamic lung hyperinflation (DH) during symptom-limited incremental and constant work exercise with cycle ergometer and treadmill. The increase in end-expiratory lung volume seems to be the best predictor of dyspnea. WebVentilation during exercise was limited by mechanical constraints on V t expansion in both R and NR, that is, by dynamic hyperinflation from below and by the TLC envelope mentioned earlier here.
