## **Core Concept**
The rate of rescue breathing in adults is a critical component of cardiopulmonary resuscitation (CPR) and is guided by the American Heart Association (AHA) and other international resuscitation councils. Proper ventilation rates are essential to ensure adequate oxygenation and prevent hyperinflation of the lungs.

## **Why the Correct Answer is Right**
The correct rate of rescue breathing in an adult during CPR is **10-12 breaths per minute**. This rate is recommended because it helps to maintain a balance between providing sufficient oxygenation and minimizing the risk of gastric inflation and hyperinflation of the lungs. The AHA emphasizes that each breath should be given over one second and should raise the chest.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option suggests a rate that is too high, which could lead to hyperinflation of the lungs and increased risk of gastric inflation.
- **Option B:** Similarly, this option also suggests a rate that might be too rapid for effective and safe rescue breathing in adults.
- **Option D:** This option suggests a rate that is lower than recommended, potentially leading to inadequate oxygenation.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that during CPR, the rescuer should provide breaths at a rate of **10-12 breaths per minute** for adults, ensuring each breath is given over one second and results in a visible chest rise. This is crucial for effective CPR and improving outcomes.

## **Correct Answer:** C. 10-12 breaths per minute.
