Respiratory failure & ventilation

Continuous On-Demand Diaphragm Neurostimulation to Prevent Diaphragm Inactivity During Mechanical Ventilation: A Phase 1 Clinical Trial (STIMULUS)

Am J Respir Crit Care MedPublished Phase 1 clinical trial

Authors' conclusion

Continuous on-demand diaphragm neurostimulation-assisted mechanical ventilation is feasible and can prevent diaphragm inactivity during mechanical ventilation.
