 Egan's Fundamentals of Respiratory Care 525

COPDn(i.e., patients with heterogeneous emphysema that is uppernlobe–predominant and who have low exercise capacity afternpulmonary rehabilitation), LVRS can prolong survival, improvenquality of life, and increase exercise capacity.LVRS shouldnnot be considered in individuals with very severe COPD (i.e.,ncharacterized by FEV1 <20% predicted with either a homogeneous pattern of emphysema or a diffusing capacity <20% predicted), because the mortality rate of LVRS is higher in suchnindividuals than in medically treated patients.

Additional therapies for individuals with end-stage COPDninclude lung transplantation and lung volume reductionnsurgery (LVRS)(C)不可取代肺移植 ,in which small portions of emphysematousnlung are removed to reduce hyperinflation and improve lungnmechanics of the remaining tissue. COPD is the most commonncurrent indication for lung transplantation.
