What should be the frequency of breaths during CPR?

The recommended frequency of breaths during CPR is 2 breaths after every 30 compressions. This approach forms part of the established guidelines for high-quality CPR, which emphasize maintaining a balance between chest compressions and ventilations. The compression-to-ventilation ratio of 30:2 is essential for optimizing blood circulation and oxygen delivery during cardiac arrest.

In this ratio, 30 compressions help to create an effective blood flow, while the subsequent 2 breaths provide crucial oxygen to the lungs, which is vital during the resuscitation process. Adhering to this ratio ensures that the rescuer can deliver rapid and effective care, which is critical in life-threatening scenarios. The guideline aims to minimize interruptions in chest compressions while ensuring the patient receives adequate ventilation.
