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

In adult cardiopulmonary resuscitation (CPR), the recommended compression-to-ventilation ratio is 30:2. This ratio means that for every 30 chest compressions administered, two rescue breaths should be given. This approach is based on extensive research and guidelines established by the Resuscitation Council UK and other authoritative bodies, emphasizing the importance of maintaining high-quality chest compressions while also ensuring adequate ventilation when necessary.

The rationale behind the 30:2 ratio is to optimize the effectiveness of both components of CPR. Chest compressions are critical in maintaining blood flow to vital organs during cardiac arrest, and delivering them at a rapid pace ensures that circulation continues. Meanwhile, the addition of rescue breaths helps to provide oxygen to the lungs, which is essential for the patient's recovery when spontaneous circulation resumes.

While other compression-to-ventilation ratios might be utilized in specific scenarios or for different age groups, the 30:2 ratio for adults strikes a balance that has been shown to improve outcomes in resuscitation efforts. Ensuring adherence to this guideline is vital for anyone performing CPR to maximize the chances of survival and good neurological outcomes for the patient.
