CPP-Guided Survival Function

Kaplan-Meier curve for the time until coronary perfusion pressure (CPP) < 15 mm Hg within the SNPeCPR and standard CPR cohorts. Our data suggest that after 20 min of CPR (within 10 min of ACLS initiation). CPP drops below 15 mm Hg much faster in the standard CPR cohort. CPp < 15 mm Hg has been adversely related to achieving ROSC (23). SNPeCPR delays the decay of CPP to below ROSC threshold. sCPR = standard cardiopulmonary resuscitation; other abbreviations as in Figures 1 and 2.
