Examples of tracings from one representative patient. From top to bottom, airway pressure (Paw), flow and electrical activity of the diaphragm (EAdi) tracings of a representative patient are shown during pneumatically triggered pressure support (PS P ), neurally adjusted ventilatory assist (NAVA) and neurally controlled pressure support (PS N ). The arrow indicates an ineffective effort during PSP
