What is the standard CPR ratio of compressions to breaths described in the material?

• A. 30 compressions to 2 breaths
• B. 2 compressions to 30 breaths
• C. 15 compressions to 2 breaths
• D. 30 breaths to 2 compressions

Answer: (A)

In CPR, you first keep blood circulating with chest compressions, then provide breaths to oxygenate. The standard rhythm taught for a single rescuer performing adult CPR is 30 chest compressions followed by 2 rescue breaths, repeated in cycles. This balance maximizes perfusion while delivering enough oxygen without long pauses. The other patterns either reverse the ratio or reflect scenarios with two rescuers (where some guidelines use 15 compressions to 2 breaths), but the material in question describes 30 compressions to 2 breaths as the standard.
