Written by Aaron Lacy Spoon Feed Why does this matter? What’s the best way to bump-bump-bump to ‘Stayin’ alive?’ An automated algorithm devised to detect adherence to chest compression strategy was applied to the 26,810 patients included in the original RCT. Overall, 54.4% adherence was noted for the CCC strategy (n = 12,276) versus 48.3% for the 30:2 strategy (n = 7,037). These numbers show that a CCC strategy is easier to adhere to but also show there is low adherence to either strategy overall. While the original study showed no difference between CCC and 30:2, when controlled for adherence, an intended CCC strategy had a lower OR for survival (OR 0.72, 95% CI 0.64-0.81) than a 30:2 strategy (OR 1.05, 95% CI 0.90-1.22); interaction p < 0.01). So, while 30:2 seems like the better choice based on this data, focus on adhering to whatever strategy your team picks or knows well. The best strategy is to do your BLS and ACLS instructors proud and provide high quality, high compression fraction, and low interruption CPR. Source

Our Key Numbers for CPR is a compilation of all of the important numbers (CPR ratios, CPR compression rates, etc) we teach in our CPR courses. You can use this list as a study tool or as a quick reference guide. Our Key Numbers For CPR ChartHere are the latest Key Numbers for CPR. You can also download a printable copy by clicking here. It includes the latest American Heart Association guidelines for CPR compression ratios (compressions to ventilations), depth of compressions, CPR chest compression rate for adults and children, rate of rescue breathing for adults, the number of rescue breaths for a child, the infant CPR ratio, and more.
1 rescuer – 30:2
Continuous compressions at a rate of 100-120/min
100-120 chest compressions per/minute for CPR
At least one-third of the diameter of the chest At least one-third of the diameter of the chest
2 hands-on the lower half of the breastbone (sternum) 2 hands or 1 hand (optional for a very small child) on the lower half of the breastbone (sternum) 1 rescuer
1 Breath Every 6 Seconds (10 Breaths per minute) 1 Breath every 3-5 Seconds (12-20 Breaths per minute)
If you are alone with no mobile phone, leave the victim to activate the emergency response system and get the AED before beginning CPR Witnessed collapse:
Check for responsiveness – No breathing or only gasping (no normal breathing) No definite pulse felt within 10 seconds
Limit interruptions in chest compressions to less than 10 seconds

Key TermsCPR Compression to Ventilation RatioThe Compression to Ventilation CPR Ratio is the number of chest compressions given followed by the number of ventilation breaths given while performing CPR. A compression-to-ventilation CPR ratio of 30:2 means you should give 30 chest compressions followed by 2 ventilation breaths. Rate of CPR CompressionsThis is the rate or speed of CPR compressions per minute. A rate of 100/minute means the speed at which you are giving chest compressions would allow you to give 100 compressions in a minute if you did not need to stop to provide ventilations. The only time you would do chest compressions without stopping is if the victim were intubated. Typically, a single rescuer performing CPR chest compressions at a rate of 100/minute will actually perform about 75 compressions due to the need to stop and give ventilations. Depth of CompressionsThis is simply how far down the victim’s chest is compressed with each chest compression. Rescue BreathingThis is the number of ventilation breaths that are actually given each minute. This applies to victims who have a pulse but are not breathing. Learn CPR and Save a Life TodayOur goal is to help save lives by teaching people life-saving CPR skills. If everyone learned how to perform CPR and use an AED, we could decrease the number of deaths from sudden cardiac arrest. You can learn CPR quickly and easily through one of our online classes. You can take the CPR class for free, there is no obligation. |
