During NAVA, diaphragmatic electrical activity (EAdi) is used to trigger the ventilator and perform a proportional respiratory assistance. | Severe diaphragmatic dysfunction with preserved activity of accessory respiratory muscles in a critically ill child: A case report of failure of neurally adjusted ventilatory assist (NAVA) and successful support with pressure support ventilation (PSV)
