Exercise or hyperpnea-induced air trapping is referred to as dynamic hyperinflation. Patients with chronic obstructive pulmonary disease (COPD) are particularly susceptible to dynamic hyperinflation. Common questions include:
●What causes dynamic hyperinflation?
●What are its clinical manifestations?
●How is it diagnosed?
●What is the treatment?To continue reading this article, you must log in with your personal, hospital, or group practice subscription. For more information on subscription options, click below on the option that best describes you:
