Comparing two ventilation modes for ICU patients

Comparative Analysis of Ventilation Distribution in Intensive Care: Mandatory Minute Ventilation Versus Synchronized Intermittent Mandatory Ventilation Using Electrical Impedance Tomography"

Observational Harran University · NCT06961227

This study is trying to see which breathing support method, SIMV or MMV, works better for stable adult ICU patients by switching them between the two and monitoring their lung function.

What this trial studies

This observational study evaluates the effectiveness of two mechanical ventilation modes, Synchronized Intermittent Mandatory Ventilation (SIMV) and Mandatory Minute Ventilation (MMV), in adult ICU patients who are hemodynamically stable. The study utilizes Electrical Impedance Tomography (EIT) to monitor lung ventilation and perfusion in real-time, allowing for a detailed comparison of the physiological impacts of each ventilation mode. Patients will switch between SIMV and MMV to assess which mode provides better respiratory support without the need for investigational interventions.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who are intubated, hemodynamically stable, and require mechanical ventilation without neuromuscular blockade.

Not a fit: Patients who are pregnant, have neuromuscular diseases, unstable hemodynamics, or require high PEEP may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve mechanical ventilation strategies, leading to better respiratory outcomes for critically ill patients.

How similar studies have performed: Previous studies have shown the effectiveness of similar ventilation approaches, but this specific comparison using EIT is novel.
