Consequences of dynamic hyperinflation.
| Negative consequences of dynamic hyperinflation | |
| (i) Increased elastic and threshold loading on the inspiratory muscles | | (ii) Increased work and O2 cost of breathing | | (iii) Functional inspiratory muscle weakness and possible fatigue | | (iv) Mechanical constraint on tidal volume expansion | | (v) Early ventilatory limitation to exercise | | (vi) Increased neuromechanical uncoupling of the respiratory system | | (vii) CO2 retention and possibly arterial hypoxemia | | (viii) Potential adverse cardiovascular consequences | | (ix) Increased dyspnea and exercise intolerance | |
