This study demonstrates that PMI and ΔPocc are effective in predicting weaning outcomes in patients with DT≥2mm. The effectiveness of P0.1 in assessing weaning is also significantly higher in this subgroup.

These findings suggest that diaphragm function significantly influences the accuracy of predicting weaning outcomes based on respiratory drive and inspiratory effort.

This highlights the need for future research to explore the comprehensive effects of these factors within individualized patient populations and their specific characteristics.

This observational case-control study enrolled patients on mechanical ventilation for more than 48 h and completed a 30-minute spontaneous breathing trial (SBT) with pressure-support ventilation for the first time.
