Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Neurally adjusted ventilatory assist (NAVA) is an FDA approved mode of mechanical ventilation. This mode of ventilation is currently in routine use in adult, pediatric and neonatal intensive care units. The electrical activity of the diaphragm, the largest muscle used during inspiration, is measured. The ventilator triggers (synchronizes patient effort) and applies proportional assistance based on measured electrical activity of the diaphragm (Edi). This electrical activity is measured through a feeding tube that also has a multiple-array esophageal electrode in it. This mode of ventilation has been proven to be equivalent to pressure support ventilation (PSV). Theoretically, the breath-to-breath control offered by NAVA may not only trigger faster and synchronize better, but provide the support deemed appropriate by the central nervous center on demand. Traditionally in the intensive care unit (ICU), pressure support is applied to subject breathing spontaneously. Pressure is set to achieve a given tidal volume. The influence of changing lung compliance not only from the lung disease itself, but the interactions of the respiratory muscles can drastically change minute ventilation and contribute to hyper- or hypoventilation. These changes are typically found on assessment of end-tidal carbon dioxide (CO2), blood gas, or oxygen saturation (SpO2) monitoring; all of which are potentially preventable if we allowed the central nervous system to control the ventilator. NAVA may allow us to couple the central nervous system (neuro-coupling) with the ventilator to provide real-time proportional assistance, reduce work of breathing and apply physiologic breathing patterns.
