Filter by:Protective ventilatory strategy should be applied to reduce both ventilator-induced lung injury (VILI) and ventilator-induced diaphragm dysfunction (VIDD) after Lung Transplantation (LTx). 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.
There is little evidence about the mechanical characteristics and muscular function in patients with Acute Respiratory Distress Syndrome (ARDS) at the time of weaning of the mechanical ventilation, as well as the behavior of the mechanical properties, breathing pattern, muscular effort, and gas exchange during a successful and failed spontaneous breathing trial.
This study is aimed at evaluating patient work of breathing and tidal volumes with three methods of oxygenation: standard oxygen, high-flow oxygen therapy and non-invasive ventilation.
Primary Graft Dysfunction (PGD) respresents the leading cause of mortality in early post-operative period of Lung Tranplantation (LTx). Protective ventilatory strategy could potentially reduce the risk of PGD in these patients. Neurally Adjusted Ventilatory Assist (NAVA) is an assisted ventilation mode that could allow to adopt this strategy. Aim of the study is to assess the feasibility of NAVA in the early post-LTx phase and to describe the breathing pattern and the physiological relationship between neural respiratory drive and different levels of ventilatory assist, in the absence of pulmonary vagal afferent feedback.
