Physiology of Neurally Adjusted Ventilator Assist (NAVA)

"Neurally adjusted ventilator assist (NAVA) is an advanced mode of mechanical ventilation that delivers pneumatic support proportional to, and synchronized with, the patient's electrical neural respiratory output, captured via the electrical activity of the diaphragm ($\text{Ea}_{\text{di}}$). By integrating real-time neural signals with mechanical delivery, NAVA bridges the gap between patient respiratory drive and ventilator response, fundamentally altering how clinicians manage critically ill patients requiring respiratory support. Introduction to Neurally Adjusted Ventilator Assist Traditional mechanical ventilation modes—such as pressure..."
