quality" CPR?)

, 2
Ans: 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.

QUESTION: What does the AHA suggest as a target for CPP (coronary
perfusion pressure) to increase the chances of SROC (spont. return
of circulation)?
Master01 | 2025/2026 | Latest update
, 3
Ans: It is recommended that the CPP be 10mm/Hg to give the best chances for
achieving SROC.
This requires "high-quality CPR".

QUESTION: An end-tidal CO2 reading of ____ will not achieve ROSC
according to the AHA.
Ans: 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.

QUESTION: An intra-arterial relaxation pressure of < ____ indicates
ineffective compressions.
Master01 | 2025/2026 | Latest update
, 4
Ans: Intra-arterial relaxation pressures of < 20mmHg correlate with poor CPP
(coronary perfusion pressure) and ineffective compressions.
Reference: 2010 AHA Guidelines
QUESTION: The recommended sternal compression depth for an
adult during resuscitation is _____ inches.
Ans: 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
QUESTION: AHA recommends that, during resuscitation, the tidal
volumes for adults be between ______ and ______ mmHg.
