About this trial

While mechanical ventilation can be used to sustain life in those with lung injury, it, can further worsen lung injury or prevent lung healing resulting in high morbidity and mortality as seen in Acute Respiratory Distress Syndrome (ARDS).

Using extracorporeal membrane oxygenation (ECMO), the highest level of life support also known as the heart-lung machine, investigators may minimize injury from mechanical ventilation to allow the lungs to heal; however, the optimal ventilator strategies while on ECMO are unknown. This study will evaluate personalized ventilator strategy compared to standard of care ventilation.

Trial outcomes

Primary outcomes

1

Biomarker outcomes (IL-6 and sRAGE)

IL-6 is a marker of systemic inflammation, previously used in studies of ECMO and ARDS. sRAGE is a marker of systemic inflammation and acute lung injury, previously used in studies of ECMO and ARDS.

Time frame
Baseline at enrollment, 24±12 hours post enrollment, 48±12 hours post enrollment, 72±12 hours post enrollment, and end of ECMO run.
2

Respiratory gas exchange (dead space, oxygenation).

Arterial oxygenation (mmHg) will be assessed with the arterial blood gas. Deadspace fraction (unitless) will be calculated by the end-title CO2 monitoring.

Time frame
Baseline at enrollment, 24±12 hours post enrollment, 48±12 hours post enrollment, 72±12 hours post enrollment.
3

Respiratory mechanics (compliance of the respiratory system, tidal volume, and imaging)

Compliance (ml/cmH2O) and tidal volumes (milliliters) will be measured by the ventilator. Imaging assessed will be the daily chest x-ray.

Time frame
Baseline at enrollment, 24±12 hours post enrollment, 48±12 hours post enrollment, and 72±12 hours post enrollment.

Secondary outcomes

1

Exploratory plasma, urine, and respiratory biomarkers.

Exploratory plasma biomarkers include but are not limited to: angiopoietin-1, angiopoietin-2; chemokind ligand-9, interferon-α; interferon γ-inducible protein-10, tumor necrosis factor α, vascular endothelial growth factor levels, etc.

Time frame
Baseline at enrollment, 24±12 hours post enrollment, 48±12 hours post enrollment, 72±12 hours post enrollment, and end of ECMO run.
