From: Lung protection during non-invasive synchronized assist versus volume control in rabbits
Experimental set up and experimental recordings. Left panels show experimental set-up and physical placement of interfaces and right panels show experimental recordings for each mode. Volume control (VC, top) and non-invasive ventilation-neurally adjusted ventilatory assist (NIV-NAVA, bottom). VC setup: ventilator was connected to the endotracheal tube at the tracheostomy to measure ventilator pressure (Pvent). NIV-NAVA setup: Ventilator was connected to the nasal prong (Pprong), where ventilator-delivered pressure was measured. Tracheal pressure (Ptr) was also measured via a side-port at the tracheotomy. PEEP, positive end-expiratory pressure; EAdi, electrical activity of the diaphragm.
