Decannulation criteria in patients with acquired brain injury based on interval forced vital capacity monitoring: a prospective observational study
Criteria for Decannulation in Tracheostomized Patients with Acquired Brain Injury
Overview
This study investigates the relationship between changes in forced vital capacity (FVC) and successful decannulation in tracheostomized patients with acquired brain injury (ABI). A significant finding is that an increase in FVC of 1 L is associated with a reduction of 8.7 days to decannulation, with a notable threshold effect at a ΔFVC of 0.52 L.
Background
Acquired brain injury (ABI) is a leading cause of disability and mortality, often necessitating tracheostomy due to respiratory failure. Determining the optimal timing for decannulation is crucial, as both premature and delayed decannulation can lead to serious complications. Current practices lack standardized physiological criteria.

Mean Age

ΔFVC Association with Decannulation Time
8.7 days shorter per 1-L increase
Threshold for ΔFVC
0.52 L
Key Findings
56 patients with ABI were enrolled in the study.
Each 1-L increase in ΔFVC was associated with a reduction of 8.7 days to successful decannulation.
A significant threshold effect was observed at ΔFVC = 0.52 L.
Below the threshold, the association was stronger (β = -13.616 days/L).
Above the threshold, the association was non-significant (β = -2.244 days/L).
Clinical Implications
Interval monitoring of FVC may provide a valuable tool in assessing decannulation readiness in patients with ABI. The identified threshold of ΔFVC = 0.52 L could serve as a reference point for initiating comprehensive evaluations for decannulation.
Conclusion
The study suggests that FVC monitoring can aid in determining decannulation timing in tracheostomized patients with ABI, particularly with the identified threshold for ΔFVC.
