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.
Keep in mind, there needs to be complete chest recoil or CPP will remain sub-optimal.
Reference: 2010 AHA Guidelines
AHA recommends that, during resuscitation, the tidal volumes for adults be between ______ and
______ mmHg. - ANSWER Adult Vt's should be between 500 - 600 mmHg which correlates to about 1/2
the squeeze of an adult ambu-bag.
Reference: 2010 AHA Guidelines
What 4 negative consequences of excessive ventilation does the AHA emphasize? - ANSWER Excessive
ventilation can cause:
- gastric inflation
- increased intrathoracic pressures
