Effect of Extubation on Respiratory Function

The extubation phase is a risky period of anesthesia management. During this step, serious complications can arise: hypoxemia, laryngospasm, pharyngeal obstruction, pneumonia… In spite of these complications, extubation and its impact on respiratory function, particularly on the Functional Residual Capacity (FRC), remains poorly studied because of the difficulty to make bedside measurements. The PulmoVista 500 is a clinical routine which provide effective non-invasive bedside measurements. It would be interesting to evaluate the impact of extubation on respiratory function, and more specifically FRC changes during and after extubation. This study will allow a better physiopathological knowledge and a quality improvement patient extubation management.
