BACKGROUND Neurally Adjusted Ventilatory Assist (NAVA) is a synchronised mode of ventilation intended for use in spontaneously breathing infants. NAVA can be used as both a Non-Invasive and Invasive mode via the Servo-n Getinge ventilator. [...] Note that nasal insertion of Edi catheter is preferred. 9. Connect Edi catheter to Getinge Servo-n Edi module and cable. [...] • NEX is ONLY part of for the calculation of placement of Edi catheter. [...] Edi peak represents neural respiratory effort and is responsible for the size and duration of the breath. [...] o In an infant requiring higher percentage of back-up and having increasing periods of ‘no patient effort’ it is important to assess what the Edi peak trends have been as this could be a sign of the baby being under or over supported . [...] o If Edi min is consistently greater or equal to 3, consider increasing PEEP to reduce the tonic activity of the diaphragm and to maintain Functional Residual Capacity. [...] o The benefit or nursing an infant on NAVA level of 0 is that if patient becomes apnoeic and has no respiratory effort, back up mode will still be triggered. [...] On smaller babies, it is not uncommon that P waves will still be pronounced in the bottom waveform due to span of electrodes and cardiac interference. [...] o The catheter insertion positioning tool will indicate if movement of the Edi catheter needs to occur (Picture 12 and 13).

The site should be rotated weekly, and the catheter cleaned with sterile water and dried with gauze prior to reinsertion.
