What are the two steps of hands-only CPR?

• A. Push down five inches and slow to 60 compressions per minute.
• B. Push down two inches and fast at 100–120 compressions per minute, allowing the chest to return to normal position.
• C. Lightly tap the chest and call 9-1-1.
• D. Use mouth-to-mouth ventilation first.

Answer: (B)

Hands-only CPR focuses on delivering high-quality chest compressions to keep blood circulating until help arrives. The best approach is to push on the chest about two inches (roughly 5 cm) with a fast pace of 100–120 compressions per minute, and to allow the chest to return fully to its normal position between compressions. This combination maximizes blood flow and ensures the heart refills properly after each compression. Because hands-only CPR uses no breaths, it’s not about mouth-to-mouth ventilation first, and options suggesting shallower or deeper depths, or a slower rate, don’t optimize blood flow or match the hands-only method.
