Background: It is largely undocumented how long it takes to wean from invasive mechanical ventilation (IMV) with tracheostomy and to what extend these patients suffer from dyspnea or discomfort and how often sputum retention occurs requiring burdensome endotracheal suctioning. In patients undergoing invasive mechanical ventilation via endotracheal tube, dyspnea is prevalent and associated with poorer quality of life and more symptoms of post-traumatic stress disorder (PTSD) Objectives: The present study aims to assess the duration of the weaning period, and the prevalence and severity of dyspnea and discomfort in patients with tracheostomy-facilitated weaning. Study design: Prospective observational multicenter cohort study. Study population: Tracheostomized critically ill patients weaning from IMV. Main study parameters/endpoints: Prevalence and severity of dyspnea and discomfort during weaning, duration of weaning with tracheostomy, frequency of endotracheal suctioning, time with tracheostomy, clinical outcomes, and mortality rates. Long term outcomes are the prevalence quality of life, PTSD, anxiety and fear.

Daily dyspnea score during weaning
Timeframe: During repeated disconnection sessions in the first 28 days after initiation of weaning with tracheostomy, once daily an assessment is made using Visual Analog Scale for Dyspnea. (0-10). Higher scores indicate higher levels of dyspnea.
Daily presence of dyspnea during weaning
Timeframe: During repeated disconnection sessions in the first 28 days after initiation of weaning with tracheostomy, once daily an assessment is made by asking communicative patients if they experience dyspnea.
