BACKGROUND: Early tracheostomy decannulation prevents complications, but premature removal poses risks. While various methods exist to assess readiness, the predictive role of pulmonary function tests remains unclear.
METHODS: This exploratory prospective observational study enrolled 46 patients at Chang Gung Memorial Hospital, Taoyuan, from March 2020 to December 2023. Participants underwent pulmonary function and coughing ability assessments-including forced vital capacity (FVC), peak expiratory flow rate (PEFR), maximum expiratory pressure (MEP), and oxygen saturation (SpO2)-prior to decannulation. Success was defined as no reinsertion within 60 days. Logistic regression analysis and receiver operating characteristic (ROC) curve analysis were performed.
RESULTS: Factors associated with a successful outcome were younger age, male sex, strong cough function, no nasogastric tube, and higher albumin levels. Key respiratory-function metrics (higher MEP, PEFR, FVC, and SpO2) were significantly linked to successful decannulation. FVC (≥ 1.35 L) and PEFR (≥ 95 L/min) strongly predicted success, with a combined metric (FVC + PEFR + MEP) achieving the highest accuracy.
CONCLUSION: For patients with an average tracheostomy duration of > 300 days, FVC, PEFR and MEP are feasible predictors of successful decannulation. Further studies are needed to validate these results.
