Cardiopulmonary Resuscitation (CPR) Practice 2025 - Free CPR Practice Questions and Study Tips.

The compression-to-breath ratio for child CPR is 30 compressions to 2 breaths. This ratio is established in accordance with the guidelines provided by organizations such as the American Heart Association. The rationale behind this specific ratio is to ensure that there is a sufficient number of chest compressions, which are critical for maintaining blood flow to vital organs during a cardiac arrest, while still incorporating breaths to deliver oxygen to the lungs.

In children, delivering effective compressions at the correct depth and rate is crucial, and the 30 to 2 ratio allows for an effective combination of these compressions along with rescue breaths. This balance helps to optimize the chances of survival by providing both the circulatory support necessary and the oxygenation that the body needs during a life-threatening emergency.

Other ratios, such as 15 compressions to 2 breaths or variations thereof, are typically applied in different contexts, such as in two-rescuer scenarios for infants. However, when performing CPR alone on a child, the ratio of 30:2 is the standard, emphasizing the importance of high-quality compressions along with rescue breaths. This method is crucial in ensuring that both circulation and ventilation are maintained effectively until advanced medical help can arrive.
