Timing of Breathing Trials for Patients on Ventilators

Impact of Spontaneous Breathing Trial Timing on Outcomes in Mechanically Ventilated Adult Patients

Not applicable Interventional Rush University Medical Center · NCT06561295

This study tests whether doing breathing trials earlier in the morning helps adult patients on ventilators recover faster and leave the ICU sooner compared to doing them later in the morning.

What this trial studies

This study investigates how the timing of Spontaneous Breathing Trials (SBTs) influences recovery in adult patients on mechanical ventilation in the ICU. It compares outcomes between patients who undergo SBTs early in the morning versus those who have them later in the morning. The goal is to determine the optimal timing for these trials to minimize the duration of mechanical ventilation and improve overall recovery metrics, including ICU stay and hospital discharge times.

Who should consider this trial

Good fit: Ideal candidates are adults aged 21 years or older who have been on mechanical ventilation for more than 48 hours and have completed at least one SBT.

Not a fit: Patients intubated for surgical procedures, those with a tracheostomy, or receiving VV-ECMO may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved recovery times and reduced reliance on mechanical ventilation for ICU patients.

How similar studies have performed: While there is variability in SBT timing practices, this specific comparison of early versus later morning trials has not been extensively tested in prior studies.
