Assessing oxygen consumption and weaning success in ICU patients on mechanical ventilation

Oxygen Consumption (VO2), Effort, and Weaning in the Mechanically Ventilated Patient in the Intensive Care Unit (ICU): EXTUBATE Study

Leiden University Medical Center · NCT06391424

This study is testing if measuring oxygen levels can help doctors better predict when patients on mechanical ventilation in the ICU can safely breathe on their own without needing to be re-intubated.

What this trial studies

This observational study focuses on patients who have been mechanically ventilated for over 72 hours and aims to improve the prediction of successful extubation. It evaluates the use of end-tidal oxygen measurements to calculate oxygen consumption (VO2) alongside other parameters like work of breathing and pressure time product. By identifying better predictors of weaning success, the study seeks to reduce the high rates of re-intubation and associated complications. The research is conducted at the Leiden University Medical Center following specific protocols for spontaneous breathing trials.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years who have been mechanically ventilated for more than 24 hours and are hemodynamically stable.

Not a fit: Patients with severe chronic obstructive pulmonary disease or significant heart failure that complicates the weaning process may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved extubation strategies, reducing the risk of re-intubation and enhancing patient outcomes in the ICU.

How similar studies have performed: Other studies have explored various parameters for predicting weaning success, but this specific approach using VO2 is relatively novel.
