From: Influence of weaning methods on the diaphragm after mechanical ventilation in a rat model
Force frequency relationship of the diaphragm in vitro. The weaning groups show a significant decrease in contractile force at all stimulation frequencies compared to CON and CMV. a indicates p < 0.05 SBT vs. CON, p < 0.01 PSV vs. CON and PSV/SBT vs CMV; b indicates p < 0.0001 PSV/SBT vs. CON, PSV vs. CMV and p < 0.001 SBT vs. CMV; c and d indicate p < 0.0001 PSV/SBT vs. CON and CMV; e and f indicate p < 0.0001 PSV/SBT vs. CON and p < 0.001 PSV/SBT vs. CMV. Values are shown as means and SD
