What are the 6 principles behind AHA's definition of "High-Quality CPR". (ie. What needs to be done to achieve "high-quality" CPR?) - ANSWER-High-quality CPR means: - Rate of at least 100 chest compressions/minute. - Compression depth of at least 2" in the adult victim. - Complete chest recoil after each chest compression. - Minimizing interruption in compressions. - Switching providers every 2 minutes (5 cycles of CPR). - Avoiding excessive ventilations. Reference: 2010 AHA Guidelines What does the AHA suggest as a target for CPP (coronary perfusion pressure) to increase the chances of SROC (spont. return of circulation)? - ANSWER-It is recommended that the CPP be 10mm/Hg to give the best chances for achieving SROC. This requires "high-quality CPR". Reference: 2010 AHA Guidelines An end-tidal CO2 reading of ____ will not achieve ROSC according to the AHA. - ANSWER-A PETCO2 reading of 10mm Hg or less indicates poor or inadequate CPP (coronary perfusion pressure) because chest compressions are not providing adequate circulation to the lungs to eliminate CO2.
