Final answer:
In a 2-rescuer CPR scenario for an adult with an advanced airway in place, 10 rescue breaths per minute should be administered, equating to one breath every 6 seconds to ensure adequate ventilation.
Step-by-step explanation:
When it comes to providing CPR for an adult where an advanced airway is in place during a 2-rescuer scenario, the number of rescue breaths given is different from traditional CPR. Typically, the average human respiratory rate under non-exertion conditions is 12-15 breaths per minute. However, according to the latest CPR guidelines, when an advanced airway is in place, the recommended rate is to deliver 10 breaths per minute, which translates to one breath every 6 seconds. This ensures adequate ventilation while minimizing the risk of gastric inflation and the potential for regurgitation.
