What can be a consequence of prolonged airway obstruction in COPD?

Prolonged airway obstruction in chronic obstructive pulmonary disease (COPD) can lead to impaired carbon dioxide exchange. COPD is characterized by narrowed airways and difficulty in airflow, which can prevent effective expulsion of carbon dioxide during exhalation. As a result, higher levels of carbon dioxide may accumulate in the bloodstream, leading to respiratory acidosis and other complications.

The mechanics of breathing become compromised, causing more significant difficulty in removing carbon dioxide compared to oxygen. Consequently, this impaired gas exchange can worsen the patient's overall respiratory status and is a critical concern in managing COPD. Maintaining effective ventilation is essential, and any obstruction detrimentally impacts the exchange of these gases in the alveoli.
