Cardiology & ResuscitationQuestion 30 of 100

During CPR, allowing the chest to fully recoil between compressions is important because it:

a.Increases compression rate
b.Allows the heart to refill with blood, improving the next compression's output
c.Reduces the need for ventilation
d.Prevents rib fractures entirely

Explanation

Full chest recoil lets the heart refill with blood between compressions, improving blood flow with each push. Leaning on the chest reduces venous return and lowers CPR effectiveness.
