Using the patient’s own respiratory drive to control the assistance of Servo ventilators, Getinge’s patented Neurally Adjusted Ventilatory Assist (NAVA) has elevated mechanical ventilation to an entirely new level.

During normal respiration, a spontaneous breath begins with an impulse generated by the respiratory centers in the brain. This impulse is then transmitted via phrenic nerves and electrically activates the diaphragm, leading to a muscle contraction.

The diaphragm contracts into the abdominal cavity, which leads to a descending movement, creating a negative alveolar pressure and an inflow of air.

The signal that excites the diaphragm is proportional to the integrated output of the respiratory center in the brain and controls the depth and cycling of the breath.

Based on the patient’s brain activi...
