What is the recommended compression-to-ventilation ratio in adult CPR?

The recommended compression-to-ventilation ratio in adult CPR is 30 compressions to 2 ventilations. This guideline is based on evidence suggesting that a higher frequency of compressions, paired with effective ventilations, maximizes blood flow to vital organs during a cardiac arrest. The 30:2 ratio allows for a more vigorous and continuous approach to chest compressions, which is crucial for maintaining perfusion and enhancing the likelihood of a successful outcome during resuscitation efforts.

This particular ratio is advised for use by both trained healthcare providers and lay rescuers alike. It simplifies the delivery of care, ensuring that bystanders can respond effectively without extensive training, thus promoting the importance of immediate action in emergencies. The focus on compressions being the priority, followed by ventilations, underscores the critical role that effective chest compressions play in restoring circulatory function.
