How do you get rid of co2 that stays in the lungs as with copd?

To help remove excess CO2 from the lungs in individuals with COPD, techniques such as pursed-lip breathing and diaphragmatic breathing can be beneficial. These methods promote better airflow and enhance gas exchange. Additionally, bronchodilator medications can help open the airways, making it easier to expel trapped carbon dioxide. Regular physical activity and pulmonary rehabilitation may also improve lung function and efficiency.
