Several studies have recently used data from monitor files:
• Multicenter observational study of Multicenter observational study of 506506 CPR files (largest of its kind to date)CPR files (largest of its kind to date)
• Investigated the association of Investigated the association of chest chest compression fraction compression fraction (CCF)* (CCF)* with survival with survival in patients presenting in VF/VTin patients presenting in VF/VT
• Evaluated CCF during the period prior to Evaluated CCF during the period prior to first shockfirst shock
• Conclusions: Conclusions: More time spent performing chest More time spent performing chest
compressions in the early phase of compressions in the early phase of resuscitation substantially affects survivalresuscitation substantially affects survival
Some questions are unanswered, and Some questions are unanswered, and further studies are necessaryfurther studies are necessary
