What is the appropriate compression to breath ratio for infant CPR when one rescuer is present?

In infant CPR, when only one rescuer is present, the correct compression to breath ratio is 30 compressions followed by 2 breaths. This ratio is established to ensure that adequate blood flow is maintained while also providing sufficient oxygenation to the infant's body. Compressions are critical for maintaining circulation during cardiac arrest, and the 30:2 ratio is designed to maximize the number of compressions delivered, thereby increasing the chances of successful resuscitation.

The emphasis is on delivering a high-quality chest compression rate with minimal interruption for breaths, which is particularly important in infants, as they have smaller lungs and a different anatomy that requires careful consideration during resuscitation efforts. This ratio helps address both the need for effective compressions and adequate ventilation, balancing the two aspects of CPR for the best possible outcome in emergency situations.
