Neurally Adjusted Ventilatory Assist

  • Chapter
  • First Online:
Mechanical Ventilation from Pathophysiology to Clinical Evidence

Abstract

Neurally adjusted ventilatory assist (NAVA) is a mode of assisted ventilation, proportional (i.e. the amount of support is proportional to patient’s effort), readily available in clinical practice on a specific ventilator. During NAVA, the inspiratory support is based on electrical activation of the diaphragm (EAdi) from initiation to amplitude of support and cycling off. Patient’s breathing is assisted in synchrony with, and in proportion to, the patient’s respiratory drive through EAdi. This mode may improve patient–ventilator synchrony and patient’s demand in order to improve comfort and weaning.
