Monitoring breathing effort in patients on mechanical ventilation

Monitoring of Breathing Effort Through Pressure Time Product Measurement Using Airway Occlusion Pressure

Observational Hospital Italiano de Buenos Aires · NCT06040138

This study is testing a new way to measure how hard patients on mechanical ventilation are working to breathe, to see if it can help them recover better after struggling to breathe on their own.

What this trial studies

This observational study aims to validate a non-invasive method for measuring breathing effort in patients undergoing mechanical ventilation, particularly those experiencing prolonged weaning. The researchers will utilize airway occlusion pressure to estimate the magnitude of respiratory effort and program ventilator assistance accordingly. By focusing on diaphragmatic protection strategies, the study seeks to maintain muscular effort within an optimal range, thereby improving patient outcomes. The study will include patients who have failed multiple spontaneous breathing trials and have an esophageal balloon placed for accurate measurement.

Who should consider this trial

Good fit: Ideal candidates for this study are patients on mechanical ventilation who have failed three or more spontaneous breathing trials and are hemodynamically stable.

Not a fit: Patients under 18 years old, pregnant women, or those with a do-not-resuscitate order or poor short-term prognosis may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the management of patients with respiratory failure by improving weaning strategies and reducing complications associated with prolonged mechanical ventilation.

How similar studies have performed: While the approach of using airway occlusion pressure is validated, the specific methodology of this study is novel and has not been extensively tested in similar contexts.
