Summary

Out-of-hospital cardiac arrest (OHCA) affects over 356,000 individuals annually in the United States, with fewer than 10% surviving to hospital discharge, mirroring statistics from Europe. Post-cardiac arrest syndrome (PCAS), a condition causing multi-organ dysfunction, is a leading cause of mortality despite successful resuscitation efforts. Targeted temperature management (TTM) is recommended for comatose patients post-resuscitation to mitigate PCAS, but optimal temperature targets and cooling methods remain unclear. Experimental studies suggest that therapeutic hypothermia (32-34°C), induced rapidly after resuscitation, may provide significant clinical benefits.

Total liquid ventilation (TLV) with breathable liquids has been proposed to achieve ultra-rapid therapeutic hypothermia (URTH). This approach uses the lungs as a heat exchanger to achieve ultra-rapid cooling while maintaining normal gas exchange. It enables a reduction in core body temperature to the hypothermic range (33.0 ± 0.5°C) within 45 minutes in relevant experimental models.

The OverCool study is an open-label, single-arm, multi-centric pilot trial designed to evaluate the performance and safety of Vent2Cool, a medical device intended to induce ultra-rapid therapeutic hypothermia by TLV in resuscitated cardiac arrest patients. The primary objective is to demonstrate Vent2Cool's ability to achieve a target core temperature of 33.0 ± 0.5°C within 60 minutes from start of procedure in resuscitated patients admitted to the Intensive Care Unit following intra- or extra-hospital cardiac arrest. Secondary objectives include assessing procedural safety, cooling performance, feasibility in emergency settings, clinical outcomes, and the impact on biological markers.
