What is NAVA in the NICU?
Table of Contents
Neurally-adjusted ventilatory assist (NAVA) is a relatively newer mode of ventilation in which a ventilator utilizes the electrical activity of the diaphragm (Edi) to generate appropriate breaths and assist ventilated patients.
What do NAVA levels mean?
The NAVA level is the factor by which the Edi signal is multiplied to adjust the amount of assist delivered to the patient. The set NAVA level reflects the amount of work of breathing that the ventilator will take over from the patient. Backup settings are selected to ensure respiratory support in case of apnea.

How is NAVA level calculated?
NAVA level is a conversion factor that converts the Edi signal into a pro- portional pressure. For each breath, the peak pressure is determined by the formula: Peak pressure = NAVA level x Edi (peak – min) + PEEP.
What is NIV NAVA NICU?
NIV-NAVA has been successfully used clinically in neonates as a mode of ventilation to prevent intubation, to allow early extubation, and as a novel way to deliver nasal continuous positive airway pressure. The use of NAVA in neonates is described with an emphasis on studies and clinical experience with NIV-NAVA.

What is NAVA catheter?
We call it Neurally Adjusted Ventilatory Assist (NAVA). It is based on close monitoring of the output of the patient’s respiratory center, by capturing the electrical signal that activates the diaphragm (Edi), using a dedicated gastric feeding tube (Edi catheter).
What is NAVA ventilation mode?
Neurally adjusted ventilatory assist (NAVA) is a new mode of mechanical ventilation that uses the electrical activity of the diaphragm (EAdi) to trigger and cycle inspiratory assistance and provide it in proportion to the patient’s effort [9,10,11,12].
When was NAVA invented?
NAVA, which has been used exclusively by Getinge since it was invented in the mid-1990s and commercially released in 2007, is based on these activities in the patient’s brain.
How does NAVA ventilation work?
Who invented NAVA?
One ventilation technique that breathes with the patient is called Neurally Adjusted Ventilatory Assist, or NAVA, developed by Getinge, a global leader in intensive care technology for both infants and adults.
What is NAV ICU?
Neurally adjusted ventilatory assist (NAVA) is a mode of mechanical ventilation. NAVA delivers assistance in proportion to and in synchrony with the patient’s respiratory efforts, as reflected by an electrical signal.
Who invented NAVA ventilation?
What is NAV ventilation?
From Wikipedia, the free encyclopedia. Non-invasive ventilation. The setup for non-invasive ventilation using a mechanical ventilator. Modern devices are often much smaller.
