Air hunger in COPD patients is primarily caused by airflow limitation and impaired gas exchange due to chronic inflammation and structural changes in the lungs. As the disease progresses, the lungs become less efficient at transferring oxygen and removing carbon dioxide, leading to hypoxemia and hypercapnia. This results in the sensation of breathlessness or air hunger, as the body attempts to compensate for inadequate oxygenation and increased work of breathing. Additionally, anxiety and psychological factors can exacerbate the feeling of air hunger in these patients.
