What is the compression-to-breath ratio for adult CPR?

The compression-to-breath ratio for adult CPR is 30:2. This means that for every 30 chest compressions delivered, 2 rescue breaths should be provided. This ratio is based on current CPR guidelines, which emphasize effective chest compressions to maintain blood circulation during cardiac arrest.

In adult CPR, the focus is on performing compressions effectively and at a rate of 100 to 120 compressions per minute. The 30:2 ratio serves to maximize blood flow while still allowing for adequate ventilation through rescue breaths. This approach ensures that enough oxygen can circulate within the body while chest compressions are sustained to support circulation.

The ratios of 15:2, 20:1, and 30:1 either reduce the number of compressions being performed relative to breaths or do not align with the most effective practices for adult resuscitation as established by the latest guidelines. Hence, understanding this correct ratio is essential for effective CPR training and practice.
