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

The recommended compression-to-breath ratio for adult CPR is 30 compressions followed by 2 breaths. This guideline is established to provide a balance between continuous chest compressions and providing ventilations to the patient. The focus on 30 compressions allows for the generation of adequate blood flow during cardiac arrest, which is critical for maintaining vital organ perfusion. Following this, delivering two breaths introduces oxygen into the lungs, which is necessary for effective resuscitation efforts.

The emphasis on this ratio stems from research indicating that high-quality chest compressions significantly improve survival outcomes in cardiac arrest cases. This method aids in minimizing interruptions to compressions, thereby maximizing blood circulation while still ensuring that the patient receives necessary ventilatory support after adequate chest compressions have been performed.
