There are often portions of the lung tissue that are more diseased than other portions. LVRS removes up to 20 to 30 percent of the most diseased tissue from the lungs at one time. Removing some of the emphysema helps the healthier areas of the lungs and muscles to function better. People often are able to exercise more and feel less short of breath following lung volume reduction surgery.
