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. Reference: 2010 AHA Guidelines An intra-arterial relaxation pressure of ____ indicates ineffective compressions. - ANSWER_Intra-arterial relaxation pressures of 20mmHg correlate with poor CPP (coronary perfusion pressure) and ineffective compressions. Reference: 2010 AHA Guidelines The recommended sternal compression depth for an adult during resuscitation is _____ inches. - ANSWER_The recommended sternal compression depth for an adult during resuscitation is 2 inches.
