Exploring different levels of ventilator support for patients with acute respiratory failure

Neural Pressure Support, a Randomized Crossover Trial

Not applicable Interventional Karolinska Institutet · NCT05670093

This study is testing different levels of breathing support for patients on a ventilator to see which helps them breathe better and feel more comfortable.

What this trial studies

This interventional study focuses on patients who have been intubated and on mechanical ventilation for over 24 hours. It employs a randomized crossover design to compare three levels of ventilatory support: baseline, 50%, and 150% of baseline, using both Pressure Support and Neural Pressure Support modes. The study aims to assess patient-ventilator synchrony and respiratory muscle unloading by recording ventilator curves and obtaining blood gas measurements at the end of each 20-minute intervention phase.

Who should consider this trial

Good fit: Ideal candidates are patients who have been intubated for more than 24 hours and are in the weaning phase from mechanical ventilation.

Not a fit: Patients with bleeding disorders, unstable circulation, severe lung disease, fever, or those who are pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve ventilator management strategies for patients with acute respiratory failure, leading to better patient outcomes.

How similar studies have performed: While the specific approach of Neural Pressure Support is novel, similar studies exploring ventilator support strategies have shown promise in improving patient outcomes.
