AHA2015: Analysis of cardiac rhythm during chest compressions compared to standard care


Main Theme: Analysis of rhythm during chest compression

TFQO: Rudolph Koster

Author(s): Alfredo Sierra & Kevin Nation EVREV
Among adults and children who are in cardiac arrest in any setting (P), does analysis of cardiac rhythm during chest compressions (I), compared with standard care (analysis of cardiac rhythm during pauses in chest compressions) (C), change Survival with Favorable neurological/functional outcome at discharge, 30 days, 60 days, 180 days AND/OR 1 year, Survival only at discharge, 30 days, 60 days, 180 days AND/OR 1 year, ROSC, time to first shock, time to commence CPR, CPR quality (O)?

  1. Papers included bibliography from 2009 to 2013
  2. Papers before 2009 were exclude because were analyzed in 2010 review
  3. From the 29 total papers we exclude 15 that were in the bibliogrphy before 2009
  4. From the 14 included papers 6 were exclude because did not have sufficient statistical data..
  5. In the 8 analyzed papers, the central topic was in 3 shock advisory systems Algorithms; 2 artefact filters and 4 hands-off time with compression pause.
  6. The quality of evidence in GRADE of the 8 papers were in 6 low and 2 very low.
  7. In the 8 papers priority evaluation was 5 important
