What is the life expectancy of a person with copd and only 23 percent of his lung capacity left?

The life expectancy of a person with COPD and only 23 percent lung capacity can vary significantly based on several factors, including overall health, comorbidities, and adherence to treatment. Generally, severely reduced lung capacity indicates a more advanced stage of the disease, which can lead to a shorter life expectancy. Patients in this condition may face significant challenges in daily activities and could experience a decline in health. It's crucial for individuals to work closely with their healthcare providers to manage their condition and improve quality of life.
