🔍 Key Concepts

• Basic life support (BLS) standards for adults regarding ventilation-only resuscitation • Typical recommended breaths-per-minute when no chest compressions are being performed • Difference between full CPR (compressions + breaths) and rescue breathing only

💭 Think About

• Think about what rate of breathing would most closely match a normal, healthy resting respiratory rate in adults. • Ask yourself: if you breathe too slowly, what happens to oxygen levels? If you breathe too fast, what happens to carbon dioxide levels and effectiveness? • Compare each option to a realistic adult breathing pattern: which choice is closest to a calm, effective rate rather than very slow or very rapid?

✅ Before You Answer

• Eliminate any rate that is clearly much slower than a normal adult breathing rate. • Eliminate any rate that is clearly much faster than a normal adult breathing rate. • Choose the option that most closely matches the typical resting adult respiratory rate range (about 12–20 breaths per minute).
