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

The recommended compression-to-breath ratio for CPR in adults is 30 compressions to 2 breaths. This ratio is established based on guidelines to ensure the most effective and efficient delivery of CPR. The emphasis on 30 chest compressions followed by 2 rescue breaths allows for a higher number of compressions to be administered within a shorter time frame, which enhances blood circulation and increases the likelihood of returning spontaneous circulation.

The rationale behind this specific ratio is that chest compressions are crucial for maintaining blood flow to vital organs, particularly the brain and heart. By prioritizing compressions with this ratio, medical providers can perform effective CPR while minimizing interruptions for ventilations, thereby maximizing the overall effectiveness of resuscitation efforts. This method strikes a balance between oxygenating the patient and maintaining perfusion through compressions.
