Acute diaphragmatic shortening: in vitro mechanics and fatigue.

In acute hyperinflation, the occurrence of diaphragmatic shortening may alter the contractile characteristics and function of the diaphragm. The aim of this study was to investigate the effects of acute passive diaphragmatic shortening on in vitro mechanical properties and fatigability. Optimal diaphragmatic length (Lo) was defined as being that length at… (More)
