In a study by Weil Institute of Critical Care Medicine, The researches found that cooling the cranium (In the study they sprayed coolant into the nasal cavity) showed that the subjects had immediate post ROSC (return of spontaneous circulation) benefits of increased arterial pressure and increased coronary perfusion pressure (CPP), and were less likely to return to ventricular fibrillation (in the study, 50 percent less likely!)
Overall core temperatures remained the same. Brain temperatures in the cooled subjects were approximately 3 degrees centigrade cooler, however.
"Conclusion: In this model, selective head cooling rapidly reduces brain temperature during CPR. These reductions in brain temperature increase arterial and CPP immediately following ROSC, resulting in greater hemodynamic stability and less recurrence of VF."
