Open Access Abstract Introduction Physiological determinants of weaning success and failure are usually studied in ventilator-supported patients comparing those who failed a trial of spontaneous breathing with those who tolerated such a trial and were successfully extubated. A major limitation of these studies was that the two groups may be not comparable concerning the severity of the underlying disease and the presence of comorbidities. In this physiological study we assessed the determinants of weaning success in patients acting as their own control once they are eventually liberated from the ventilator. Methods In 30 stable tracheotomised ventilator-dependent patients admitted to a weaning center inside a respiratory intensive care unit we recorded the breathing pattern respiratory mechanics inspiratory muscle function .
