When performing CPR on an adult, what is the recommended compression to ventilation ratio?

The recommended compression to ventilation ratio for performing CPR on an adult is 30 compressions to 2 breaths. This ratio is established to ensure that the emphasis is placed on high-quality chest compressions, which are critical for maintaining blood flow and providing oxygen to the vital organs during cardiac arrest.

The rationale behind this specific ratio is that it allows for a rapid sequence of 30 compressions, which helps to circulate blood effectively, followed by 2 breaths to provide oxygen to the lungs. This combination maximizes the chances of reviving a person in cardiac arrest by balancing the need for both circulatory support and oxygenation.

Moreover, the guideline stipulates that this ratio applies in scenarios where a single rescuer is performing CPR. In cases involving multiple rescuers, the compression to ventilation ratio may differ; however, for a single rescuer, 30:2 is the standard approach taught in CPR courses. Understanding this ratio is crucial for effective CPR and improving outcomes during cardiac emergencies.
