    ObjectiveTo describe the variables related to effective cough capacity and the state of consciousness measured prior to decannulation and compare their measured values between the different areas of care such as the Intensive Care Unit (ICU), General ward and Mechanical Ventilation Weaning and Rehabilitation Centers (MVWRC). Secondarily analyze the evolution of patients once decannulated.DesignCase series, longitudinal and prospective.ScopeMulticentric 31 ICUs (polyvalent) and 5 MVWRC.PatientsTracheostomized adults prior to decannulation.MeasurementsMaximum expiratory pressure, peak expiratory flow coughed (PEFC), Glasgow Coma Scale (GCS).ResultsTwo hundred and seven decannulated patients, 124 (60%) in ICU, 59 (28%) General ward and 24 (12%) in MVWRC. The PEFC presented differences between the patients (ICU 110 - 190 l/min versus MVWRC 167.5 - 232.5 l/min, p <.01). The GCS was different between General ward (9 -15) versus ICU (10-15) and MVWRC (12-15); p <.01 and p <.01, respectively. There were differences in the days of hospitalization (p <.01), days with tracheostomy (<0.01) and the number of patients referred at home (p =.02) between the different scenarios.ConclusionThere are differences in the values of PEFC and GCS observed when decannulating between different areas. A considerable number of patients are decannulated with values of PEFC and maximum expiratory pressure below the suggested cut-off points as predictors of failure in the literature. No patient in our series was decanulated with an GCS <8, this reflects the importance that the treating team gives to the state of consciousness prior to decannulation.Copyright © 2018 Elsevier España, S.L.U. y SEMICYUC.
