Question 1

What is the recommended action if a trained rescuer cannot deliver rescue breaths due to a barrier device not being available?

Accepted Answer

Perform hands-only CPR with continuous chest compressions

Answer

If no barrier device is available, AHA recommends hands-only CPR (continuous compressions at 100–120/min) rather than no CPR at all.

Question 2

When integrating an AED with CPR, when should compressions be paused?

Accepted Answer

Only while the AED is analyzing the rhythm and delivering a shock

Answer

Compressions must pause during AED rhythm analysis and during shock delivery, but should resume immediately after the shock with minimal interruption.

Question 3

What is 'CPR quality' and why does it matter?

Accepted Answer

Delivering compressions at the correct rate, depth, and recoil with minimal interruptions to maximize perfusion

Answer

High-quality CPR — correct rate (100–120/min), adequate depth (≥2 in), full recoil, minimal pauses, and avoiding excessive ventilation — directly improves survival outcomes.

Question 4

What common mistake should be avoided when giving rescue breaths?

Accepted Answer

Hyperventilating the victim with too many or too forceful breaths

Answer

Excessive ventilation increases intrathoracic pressure, reduces venous return to the heart, and can cause gastric inflation — only one breath per second producing visible chest rise is needed.

Question 5

A victim regains a pulse but is still not breathing during CPR. What should you do?

Accepted Answer

Provide rescue breathing at 10–12 breaths per minute without compressions

Answer

If a victim has a pulse but is not breathing, provide rescue breathing at a rate of 10–12 breaths per minute (one breath every 5–6 seconds) without compressions.
