Final answer:
The ratio of compressions to ventilations in an infant 2-person scenario is 30:2. During CPR, rescuers should perform 30 compressions at a rate of at least 100-120 compressions per minute followed by 2 breaths.
Step-by-step explanation:
The ratio of compressions to ventilations in an infant 2-person scenario is 30 compressions to 2 ventilations. This is based on the guidelines provided by the American Heart Association for pediatric CPR. During CPR, rescuers should perform 30 compressions at a rate of at least 100-120 compressions per minute, followed by 2 breaths.
