As lung tissue deteriorates, air gets trapped and causes the diseased region of the lung to expand, called hyperinflation. Healthy regions are compressed, and breathing becomes increasingly more difficult. Learn more about emphysema.
The Zephyr valve is designed to help you breathe more efficiently by reducing the size of the diseased lung region. This simple procedure has been clinically proven to significantly improve lung function, exercise tolerance, and quality of life.
The one-way valve prevents airflow into the diseased region during inhalation, while allowing trapped air and fluids to escape upon exhalation.
Reducing the volume of the diseased region may allow healthier regions to expand and function more efficiently.
