Synergy of Elevation of the Head and Thorax and REBOA During Out-of-Hospital Cardiac Arrest

"The REBOA device used in this study will be a computer-aided aortic balloon occlusion catheter with safety feedback and automatic inflation and deflation. The device will be used to temporarily inflate a balloon in the descending aorta through a femoral artery introducer sheath which, when inflated, redirects blood flow to the central circulation.~The REBOA will be inserted into the aorta via the femoral artery through an introducer sheath. Once positioned, the balloon will be inflated to occlude the aorta. The REBOA assistant will be attached to the patient's skin with the adhesive on the underside of the assistant."

Conventional CPR will be performed using an automated head and chest elevation device during cardiopulmonary resuscitation (AHUP-CPR).

In addition to head and thorax elevation, mechanical chest compression will be performed with active chest compression-decompression using a specific mechanical chest compression device.

In addition to REBOA, AHUP-CPR and ACD, an impedance threshold device will be used with a dedicated device.
