Proportional assist ventilation and exercise tolerance in subjects with COPD
TE Dolmage, RS Goldstein - Chest, 1997 - Elsevier
Study objective This study determined whether proportional assist ventilation (PAV) applied
during constant power submaximal exercise could enable individuals with severe but stable
COPD to increase their exercise tolerance. Design Prospective controlled study having a
randomized order of intervention. Setting Pulmonary function exercise laboratory.
Participants Ten subjects with severe stable COPD (mean [SD]: age= 59 [6] years; FEV 1=
29 [7]% predicted; FEV 1/FVC= 33 [7]%; thoracic gas volume= 201 [47]% predicted; diffusion …
