Electrical Activity of the Diaphragm and Respiratory Mechanics During NAVA

Sponsor: University of Padova

Summary

Protective ventilatory strategy should be applied to reduce ventilator-induced lung injury (VILI) after Lung Transplantation (LTx) or in case of acute respiratory failure requiring invasive mechanical ventilation. Neurally Adjusted Ventilatory Assist (NAVA) is an assisted ventilation mode in which respiratory support is coordinated by the electrical activity of the diaphragm (EAdi). Aim of the study is to assess the physiological relationship between neural respiratory drive, as assessed by EAdi, and tidal volume, driving pressure, and mechanical power, at different levels of ventilatory assist, in the absence of pulmonary vagal afferent feedback or during acute respiratory failure. Additional parameters will be collected: Pmus, Pocc, transpulmonary pressure etc.

Official title: Evaluation of the Relationship Between Electrical Activity of the Diaphragm and Respiratory Mechanics During Neurally Adjusted Ventilatory Assist in Lung Transplant Patients and in Patients Affected by Acute Respiratory Failure.
