Abstract
Objective
To assess the predictive capacity of the Rapid Shallow Breathing Index (RSBI) for success in spontaneous breathing trials (SBT) and extubation in critically ill patients. We evaluated the association between RSBI, duration of mechanical ventilation, and ventilator-free time at 28 days.
Design
Prospective multicenter observational study. Secondary analysis of the COBRE-US study.
Setting
Intensive care unit (ICU).
Patients or participants
367 patients in the ICU receiving invasive mechanical ventilation.
Interventions
Assessment of RSBI at the end of SBT.
Main variables of interest
RSBI, SBT, duration of mechanical ventilation, and ventilator-free time at 28 days were evaluated.
Results
367 patients in the ICU under invasive mechanical ventilation were evaluated, of whom 59.7% were male with a median age of 61 years (IQR: 49–72). A total of 456 SBT were conducted with a success rate of 76.5%. RSBI had a ROC-curve of 0.53 for SBT success and a ROC-curve of 0.48 for extubation. The Spearman correlation coefficient between RSBI and duration of ventilation was 0.117 (p = 0.026), while for ventilator-free time at 28 days, it was −0.116 (p = 0.028).
Conclusions
RSBI was not associated with success in SBT or extubation, regardless of the cutoff point used. Correlation analyses showed weak associations between RSBI and both the duration of ventilation and ventilator-free time at 28 days.
