When using a bag-mask device on an adult during CPR, at what rate should you deliver rescue breaths?

• A. 8-10 breaths per minute
• B. 12-14 breaths per minute
• C. 10-12 breaths per minute
• D. 6-8 breaths per minute

Answer: (C)

Deliver rescue breaths at about 10–12 breaths per minute when using a bag-mask on an adult during CPR. This pace is roughly one breath every 5–6 seconds and helps provide enough oxygen without causing hyperventilation. Each breath should last about one second and produce visible chest rise while you maintain chest compressions at the recommended rate (about 100–120 per minute). If you go faster or take too frequent breaths, intrathoracic pressure rises, which can hinder venous return and reduce circulation to the heart and brain. The other speeds are either too slow to supply adequate ventilation or too fast, increasing the risk of overventilation and its adverse effects.
