🔍 Key Concepts

• Normal adult breathing rate compared to rescue breathing rate • American Red Cross / American Heart Association basic CPR and first aid guidelines • Difference between breaths-per-minute for adult rescue breathing vs. infants/children

💭 Think About

• Which answer choices seem too slow to keep enough oxygen moving in an adult who is not breathing on their own? • Which answer choices seem so fast that you would risk over-ventilating (blowing too much air, too quickly) and putting air into the stomach instead of the lungs? • Think about the typical recommendation for how often to give one breath when doing rescue breathing on an adult, then convert that to breaths per minute.

✅ Before You Answer

• Confirm the recommended interval per breath for an adult during mouth-to-mouth rescue breathing, then do the math to get breaths per minute. • Eliminate any rate that is far below normal adult breathing (about 12–20 breaths per minute at rest). • Eliminate any rate that would clearly be too rapid to safely and effectively deliver full breaths.
