Neurally Adjusted Ventilatory Assist NAVA
Neurally Adjusted Ventilatory Assist NAVA is a mode of mechanical ventilation, where the ventilator is controlled directly by the patient’s own neural respiratory drive. The neural control of respiration originates in the respiratory center, where signals are transmitted through the phrenic nerve to create electrical activity of the diaphragm (Edi).
With NAVA, these signals are monitored using micro-electrodes in the Edi catheter which are positioned in the esophagus at the level of the diaphragm. A range of catheters in different French sizes and lengths, ensure optimized signal quality across all patient categories.
Neural Pressure Support (NPS) and NIV NPS
Neural Pressure Support NPS and NIV NPS is a complement to NAVA and NIV NAVA, delivering time-synchronized pressure support (PS), where both breath triggering and flow termination are based on the patient’s neural respiratory drive. NPS may help reduce the incidence of premature expiratory cycling and harmful eccentric diaphragm contractions, which are common with conventional flow-cycled PS. The faster pressurization rate compared to NAVA may offer advantages in managing restrictive ARDS and obstructive COPD patients.

Intended clinical purpose
The Edi catheter ENFit is intended for:
- Administrating nutrition, fluids and medications via the nasogastroenteric or oro-gastroenteric route.
- Aspiration and decompression via the naso-gastroenteric or orogastroenteric route.
- Transfer of electrical activity of the diaphragm (Edi signal) to compatible Servo ventilator
Intended clinical benefits
The clinical benefits with Edi catheter ENFit are:
- To provide monitoring of the patient’s breathing drive. Use of Edi signal to assess and monitor patient-ventilator synchrony and respiratory drive measured in microvolt (μV) per breath.
- To provide medication, hydration and nutrition for patients unable to eat or drink.
