• High-quality CPR should be recognized as the foundation on which all other resuscitative efforts are built
• Continually adjust resuscitative efforts based on the patient’s physiological response
• Capture CPR performance data in every cardiac arrest and use an ongoing CPR CQI program to optimize future resuscitative efforts
Final Consensus Recommendations Meaney et al, Circulation, 2013

![Page 30: Science Driving the Future of Basic Life Support Paris Hotel and Casino Las Vegas, Nevada Presented by: Dana Edelson, MD, MS, FAHA, FHM Medical Director](https://reader036.vdocuments.site/reader036/viewer/2022062515/56649ce55503460f949b3169/html5/thumbnails/30.jpg)
• Target CPR performance metrics:– CCF >80%– Compression rate of 100–120/min– Compression depth of ≥50 mm in adults with no residual leaning
• (At least one third the anterior-posterior dimension of the chest in infants and children)
– Avoid excessive ventilation• (Only minimal chest rise and a rate of <12 breaths/min)

Meaney et al, Circulation, 2013
![Page 31: Science Driving the Future of Basic Life Support Paris Hotel and Casino Las Vegas, Nevada Presented by: Dana Edelson, MD, MS, FAHA, FHM Medical Director](https://reader036.vdocuments.site/reader036/viewer/2022062515/56649ce55503460f949b3169/html5/thumbnails/31.jpg)
New data supports import of high quality CPR
Compression rate recommendations should likely include an upper limit
Data in support of real-time feedback is strengthened, though still no outcome benefit
Data in support of debriefing now includes a possible pediatric survival benefit
High quality manual CPR is equivalent to integrated automatic load-distributing band CPR
