The physiological basis of acute respiratory failure in COPD is now clear. Significant ventilation/perfusion mismatching with a relative increase in the physiological dead space leads to hypercapnia and hence acidosis.
How does COPD impact respiratory function?
In COPD, the airways of the lungs (bronchial tubes) become inflamed and narrowed. They tend to collapse when you breathe out and can become clogged with mucus. This reduces airflow through the bronchial tubes, a condition called airway obstruction, making it difficult to move air in and out of the lungs.
What causes respiratory failure?
Respiratory failure can be caused by: Conditions that make it difficult to breathe in and get air into your lungs. Examples include weakness following a stroke, collapsed airways, and food getting stuck in and blocking your windpipe. Conditions that make it difficult for you to breathe out.
