Despite low out of hospital cardiac arrest (OOHCA) survival rates within the UK, animal studies hint at improved cerebral blood flow via a bundled neuroprotective CPR approach.The CABARET study introduces three key devices: the Head Up Position Headwear (HUP), Active Compression/Decompression (ACD) CPR, and the Impedance Threshold Device (ITD).A survey involving 27 UK pre-hospital critical care services indicated none are using these interventions widely, either alone or bundled.The CABARET team is now initiating a pilot study to investigate the feasibility of this CPR bundle, aiming to 6.66/6RR fill the prevailing evidence void in resuscitation research.
