The ideal compression rate for adults during CPR is 100-120 compressions per minute. This range is endorsed by leading health organizations such as the American Heart Association (AHA) and is based on extensive research indicating that this rate is most effective for maintaining blood circulation during cardiac arrest.

The rationale behind this specific rate lies in the need to adequately perfuse vital organs, especially the brain and heart, with oxygen-rich blood. Compressions performed within this optimal range help to create enough pressure to facilitate blood flow, thereby improving the chances of survival and reducing the likelihood of long-term neurological damage.

Understanding the importance of this specific compression rate is crucial for anyone performing CPR, as deviations may lead to insufficient blood flow. For example, a rate that is too slow could result in inadequate circulation, while overly rapid compressions can hinder effective blood flow by not allowing enough time for the heart to refill with blood between compressions. Therefore, maintaining the compression rate within the recommended range is essential for effective CPR.
