Neurally adjusted ventilatory assist (NAVA) enhances patient-ventilator synchrony by using diaphragmatic electrical activity (Edi) to control mechanical ventilation. This optimizes respiratory muscle unloading for improved patient outcomes.
Area of Science:
- Critical care medicine
- Respiratory physiology
- Biomedical engineering
Context:
- Assisted mechanical ventilation is crucial for respiratory support.
- Traditional modes may lead to patient-ventilator asynchrony.
- Optimizing ventilator settings is key for patient recovery.
Purpose:
- To introduce and explain Neurally Adjusted Ventilatory Assist (NAVA).
- To highlight NAVA's mechanism of action based on diaphragmatic electrical activity (Edi).
- To discuss the benefits of NAVA in assisted mechanical ventilation.
Summary:
- NAVA is an advanced mechanical ventilation mode.
- It utilizes diaphragmatic electrical activity (Edi) to precisely control ventilator support.
- Inspiration is triggered and modulated by the patient's neural respiratory drive.
Impact:
- NAVA improves patient-ventilator interaction.
- It ensures optimal unloading of respiratory muscles.
- This approach offers a new paradigm for ventilator management.

Ventilatory Modes
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
