Figure 3: Electrical activity of the diaphragm: The closest signal to the respiratory center. On the left, the schema shows the nasogastric catheter with an array of electrodes positioned close to the crural diaphragm. On the right, respiratory tracings of airway pressure (Paw), flow, tidal volume and electrical activity of the diaphragm are seen as displayed on the ventilator screen
