Trial Evaluating the Interest of Noninvasive Ventilation in NAVA Mode in Respiratory Decompensations Children With Infantile Spinal Muscular Atrophy Type II

The new NAVA® ventilatory mode with the SERVO-i ventilator (Maquet®) uses the electrical activity of the diaphragm (EADi) as a marker for triggering the respiratory cycle. The EADi is captured by the electrodes of a specific catheter (the Edi® catheter) placed in the esophagus as a regular gastric feeding tube, and relayed to the SERVO-i who displays it and delivers respiratory assistance according to measured Edi signal which allows synchronous assistance, proportional to the respiratory efforts of the patient. To date, no measure of the effectiveness of NAVA NAV has been performed in children with neuromuscular pathology whereas this technique could reduce the use of invasive ventilation, very iatrogenic in these fragile subjects.
