Summary
Neurally adjusted ventilatory assist (NAVA) synchronizes breathing in infants, improving patient-ventilator interaction and reducing respiratory support needs. This method is safe and feasible for neonates and children, offering benefits over conventional ventilation.
Area of Science:
- Neonatal and Pediatric Respiratory Support
- Mechanical Ventilation Strategies
- Patient-Ventilator Interaction
Background:
- Patient-ventilator asynchrony is prevalent in neonates due to physiological challenges like small tidal volumes, high respiratory rates, and leaks.
- Leaks compromise respiratory monitoring accuracy, while infant respiratory patterns (vagal reflexes, central apnea, periodic breathing) demand adaptable ventilation.
- Neurally adjusted ventilatory assist (NAVA) offers a solution by synchronizing ventilation with the patient's neural respiratory drive.
Purpose of the Study:
- To review the physiology and recent scientific literature (since 2016) on Neurally Adjusted Ventilatory Assist (NAVA) in neonatal and pediatric populations.
- To summarize findings on both invasive and noninvasive NAVA (NIV-NAVA) and the use of diaphragm electrical activity (Edi) monitoring.
- To evaluate the safety, feasibility, and clinical outcomes associated with NAVA compared to conventional ventilation.
Main Methods:
- Systematic review of invasive and noninvasive NAVA publications since 2016.
- Analysis of studies utilizing diaphragm electrical activity (Edi) monitoring for ventilator control.
- Comparison of NAVA outcomes with conventional ventilation strategies in pediatric and neonatal patients.
Main Results:
- NAVA and Edi monitoring are feasible and safe in pediatric and neonatal populations.
- NAVA significantly improves patient-ventilator interaction compared to conventional ventilation.
- NAVA use is associated with lower peak inspiratory pressures, reduced oxygen requirements, improved comfort, less sedation, fewer apneas, and trends toward shorter hospital stays and successful extubation.
Conclusions:
- Neurally adjusted ventilatory assist (NAVA) provides effective and synchronized respiratory support for infants and children.
- Diaphragm electrical activity (Edi) monitoring enables leak-independent assessment of respiratory drive and facilitates NAVA implementation.
- NAVA represents a safe and beneficial alternative to conventional ventilation, enhancing patient comfort and clinical outcomes.

Mechanical ventilators are life-saving devices that support or replace spontaneous breathing. They deliver breaths to patients through varying methods known as ventilator modes. Understanding these modes is critical for healthcare providers managing patients with respiratory failure.
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...

Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...
