Abstract

In recent years there has been an increasing interest in the use of partial ventilatory support modes not only as weaning techniques but also in the acute phases of respiratory failure. During assisted spontaneous breathing, a variable proportion of the work of breathing is provided by the ventilator, to unload the patient’s respiratory muscles [1]. Multiple ventilator modes are currently available for assisted spontaneous breathing: among these, neurally-adjusted ventilator assist (NAVA) is undergoing extensive clinical evaluation. NAVA is conceptually different from any other mode of ventilation, since the ventilator is not controlled by the ‘pneumatic’ output of respiratory muscles (i. e., a change in airway pressure or flow) but directly by the neural activity of respiratory centers, expressed by the diaphragm electromyogram (EAdi) [2].
