What is the compression-to-ventilation ratio used by the team after Ana-Lisa resumes chest compressions?

In a two-rescuer scenario for adult CPR, the recommended compression-to-ventilation ratio is 15:2. This practice allows one rescuer to administer chest compressions while the other provides rescue breaths, ensuring that the victim receives effective ventilation alongside continuous chest compressions. This ratio helps maintain vital organs' oxygen levels while assisting circulation, which is crucial during cardiac arrest situations.

The 15:2 ratio is specifically designed for situations involving children or infants, where the emphasis on ventilation is higher due to their physiological needs. For adult victims, the standard is often referenced as 30:2, which applies when there is one rescuer performing CPR. Understanding these ratios and their appropriate contexts is essential for providing effective care in an emergency.
