In a 2-rescuer CPR scenario for an infant, what is the correct compression and ventilation cycle?

In a 2-rescuer CPR scenario for an infant, the correct compression and ventilation cycle is to provide 15 compressions followed by 2 ventilations. This guideline is crucial for ensuring that the infant receives sufficient blood flow during compressions while also allowing for effective ventilation to deliver oxygen.

The rationale behind the 15:2 ratio in this context is centered on the physiological differences and needs of infants compared to adults. Infants have a higher metabolism and oxygen demand, necessitating more frequent ventilations relative to compressions in situations where two rescuers are present. The two rescuers can efficiently alternate roles—one performing chest compressions while the other provides breaths, which allows for better management of the child's airway and ensures a higher likelihood of successful resuscitation.

In situations with different ratios, such as adults or older children, the CPR guidelines shift to a 30:2 ratio because larger body size can accommodate different physiological responses to resuscitation. Hence, the approach for infants is tailored specifically to their developmental needs, emphasizing the importance of understanding the correct technique for effective lifesaving procedures.
