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

The recommended compression-to-ventilation ratio for adult CPR is 30:2. This ratio reflects the guidelines set by the American Heart Association and is designed to provide a balance between high-quality chest compressions and effective ventilations during cardiopulmonary resuscitation.

During CPR, chest compressions are critical because they help maintain blood flow to the heart and brain when the heart has stopped beating effectively. The 30 compressions serve to circulate blood, while the 2 ventilations provide oxygen to the lungs. This sequencing maximizes the effectiveness of each part of the rescue effort, ensuring that the person in cardiac arrest receives both physical support through compressions and respiratory support through ventilations.

This ratio is recommended for adult patients because, at this age, there is generally no significant physiological reason to alter the balance between compressions and ventilations compared to children or infants, where the ratios may differ. When performing CPR, adhering to this 30:2 guideline consistently increases the chances of survival and recovery for the patient.
