Two ways to support breathing during ventilator weaning in adults

Automatic Tube Compensation vs. Pressure Support Ventilation During Spontaneous Breathing Trials in Critically Ill Adults: A Cluster-Randomized, Cluster-Crossover Trial

Not applicable Interventional Rush University Medical Center · NCT07005505

This will test whether automatic tube compensation or pressure support ventilation helps adults on a ventilator for more than 24 hours get their breathing tube removed successfully.

What this trial studies

This cluster-randomized, cluster-crossover trial at Rush University Medical Center compares pressure support ventilation (PSV) and automatic tube compensation (ATC) during spontaneous breathing trials for critically ill adults who have received invasive mechanical ventilation for at least 24 hours. Clinical units alternate which SBT mode is used as standard care, and eligible patients who pass the SBT screen receive the assigned mode as part of routine weaning. The trial tracks successful extubation after the SBT as the main outcome and records reintubation and other clinical outcomes. Both PSV and ATC are used in practice, and the trial aims to determine which mode leads to more reliable ventilator liberation.

Who should consider this trial

Good fit: Adults (18+) admitted to the ICU who have been on invasive mechanical ventilation for at least 24 hours and who pass the spontaneous breathing trial screening are ideal candidates.

Not a fit: Patients with tracheostomies, Do-Not-Intubate orders, pregnancy, prisoners, or those not being considered for extubation would not be eligible or likely to benefit.

Why it matters

Potential benefit: If one mode proves better, it could increase successful extubation rates and shorten time on mechanical ventilation, lowering related complications.

How similar studies have performed: Smaller physiologic studies and limited clinical trials suggest ATC can reduce work of breathing, but large randomized comparisons of ATC versus PSV for extubation outcomes are lacking.
