NAVA (Neurally Adjusted Ventilatory Assist)

Neurally Adjusted Ventilatory Assist (NAVA) is a advanced mechanical ventilation method that uses the body's own nerve signals from the diaphragm—the main muscle for breathing—to control breathing support. A special sensor placed in the esophagus detects electrical signals sent by the brain to the diaphragm, indicating when and how deeply a person needs to breathe. The ventilator then responds directly to these signals, providing synchronized and comfortable assistance. This approach helps ensure the ventilator's support aligns more naturally with the patient's efforts, improving comfort and potentially reducing complications associated with traditional ventilator settings.
