What is the recommended ventilation rate during CPR for adults and children?

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

Answer: (B)

During CPR, ventilation should be steady and measured to support oxygen delivery without interrupting chest compressions. The recommended rate is about ten to twelve breaths per minute, which is roughly one breath every five to six seconds. This tempo provides enough oxygenation while avoiding hyperventilation, which increases intrathoracic pressure and can reduce venous return and perfusion to the heart and brain. The same pacing works for both adults and children, and with an advanced airway you can maintain continuous compressions with breaths at about six-second intervals. In short, aim for about 10–12 breaths per minute to balance oxygen delivery with effective CPR.
