Blood doping used medication such as erythropoietin boosting the number of red blood cells in the bloodstream. Since emphysema has airflow obstruction, oxygen is not enough in the lung even though there are red blood cells increased. Blood doping doesn't help him. The rationale for lung volume reduction surgery (LVRS) is that removing emphysematous, hyperinflated areas of lung will decrease hyperinflation, improve diaphragm and chest wall mechanics, and decrease work of breathing. Bronchoscopic lung volume reduction (bLVR) was developed to collapse areas of emphysematous lung in hopes of having the same effect on respiratory function as LVRS, but without the morbidity and mortality of surgery. He should join the clinical trial.
