Hypoxic pulmonary vasoconstriction and gas exchange during exercise in chronic obstructive pulmonary disease.

abstract：STUDY OBJECTIVES:Significant morbidity and mortality offset the benefits of lung volume reduction surgery (LVRS) for emphysema. By contributing to distal lung collapse, bronchoscopic placement of valved prostheses has the potential to noninvasively replicate the beneficial effects of LVRS. The purpose of this study was...
