During CPR, what is the recommended compression to ventilation ratio for adults?

The recommended compression to ventilation ratio for adults during CPR is 30:2. This ratio is vital because it ensures that there is a sufficient number of chest compressions to maintain circulation and oxygenation to vital organs while also providing adequate ventilations to help restore a patient's breathing.

The rationale behind this specific ratio is based on research that has shown that high-quality compressions (30 compressions followed by 2 breaths) can significantly improve the chances of survival and favorable outcomes in cardiac arrest scenarios. This method allows for continuous chest compressions, which are crucial for maintaining blood flow, while also providing intermittent ventilations to supply oxygen.

In cases of adult cardiac arrest, maintaining a ratio of 30 compressions to 2 breaths helps prioritize effective circulation during the critical moments of resuscitation. This balance helps combat the effects of down time in blood flow, which can lead to brain damage or death if not addressed quickly and effectively.

Other ratios, such as 15:1, 20:2, or 40:2, do not align with current guidelines and may result in suboptimal perfusion or inadequate oxygenation, which can prolong the resuscitation attempt and increase morbidity. By adhering to the 30:2 ratio, rescu
