What is the recommended compression depth for adult CPR to meet the AHA definition of high-quality CPR?
Answer: At least 2 inches but no more than 2.4 inches
The AHA recommends 2–2.4 inches for adult compression depth; shallower depth fails to perfuse organs and deeper depth risks internal injury.
How long should a rescuer spend checking for a carotid pulse before deciding to start CPR?
Answer: No more than 10 seconds
A pulse check must take no more than 10 seconds; if absent or uncertain, CPR must begin immediately to minimize delay.
Where should the rescuer's hands be placed for adult chest compressions?
Answer: Lower half of the sternum, at the center of the chest
Placing hands on the lower half of the sternum at the center of the chest delivers effective compressions without xiphoid or rib injury.
During 2-rescuer CPR, how frequently should rescuers switch compression duties?
Answer: Approximately every 2 minutes (after 5 cycles of 30:2)
Compressor fatigue rapidly degrades compression depth and rate; switching every 2 minutes maintains the quality of high-quality CPR.
What does 'allowing full chest recoil' mean during CPR?
Answer: Releasing all downward pressure so the chest fully rises between compressions
Full recoil between compressions allows the heart to refill with blood, optimizing venous return and coronary perfusion pressure.
What is the maximum acceptable pause in chest compressions at any point during CPR?
Answer: 10 seconds
The AHA states that pauses in compressions should not exceed 10 seconds to maintain coronary and cerebral perfusion.
