The results demonstrate that this system can provide a constant inspiratory threshold load throughout inspiration with little flow resistance, and is therefore ideal for respiratory studies.}, issn = {0903-1936}, URL = {//www.qdcxjkg.com/content/12/1/208}, eprint = {//www.qdcxjkg.com/content/12/1/208.full.pdf}, journal = {European Respiratory Journal} }
