Summary

This study tests whether placing a balloon in the main artery (aorta) during CPR helps restart the heart more often than standard CPR alone. The balloon is inserted through the leg and inflated to block blood flow below the chest, potentially sending more blood to the heart and brain. Researchers are recruiting 98 adults who suffer cardiac arrest in the hospital.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: balloon catheter (REBOA) placed in the aorta
What this could lead to: If it works, this could provide a new way to improve blood flow during CPR, potentially increasing survival after cardiac arrest.
What could go wrong: This is a relatively small, early-stage trial, so results may not be conclusive. The balloon procedure itself carries risks like vessel damage or bleeding.
