Dynamic hyperinflation คือ
Webhigher (dynamic hyperinflation). This is not typically observed in healthy individuals of average fitness and thus represents a change in the normal breathing strategy during exercise. An acute increase in EELV decreases inspiratory muscle length, increases the work and oxygen cost of breathing, and decreases inspiratory muscle endurance time ... WebHyperinflated lungs are larger-than-normal lungs as a result of trapped air. It happens when you can’t exhale, or push out all of the air that’s in your lungs. The air gets trapped and takes ...

WebJun 17, 2015 · Dynamic hyperinflation is the increase in end-expiratory volume caused by incomplete end-expiratory emptying of the lungs, and intrinsic PEEP is the raised alveolar pressure during expiration which is caused by this progressive hyperinflation. This is usually caused by Increased airway resistance causing airflow limitation, but it can also ...
