What is the recommended ventilation rate for CPR in adults?

The recommended ventilation rate for CPR in adults is every 6 seconds. This guideline is based on current resuscitation protocols which indicate that during CPR, the goal is to deliver breaths that provide adequate oxygenation while allowing sufficient time for chest compressions. Ventilating every 6 seconds corresponds to a rhythm that balances the need for oxygen exchange with the critical emphasis on maintaining effective and continuous chest compressions. This approach helps optimize the chances of successful resuscitation by maintaining a high-quality compressions-to-ventilations ratio, essential in restoring circulation and improving patient outcomes.

Using shorter intervals such as every 4 or 5 seconds could impede the continuous chest compressions that are vital during CPR, while extending to longer intervals like every 7 seconds would lead to inadequate ventilation and could further delay the administration of life-saving breaths. Each breath should last about 1 second, which facilitates this recommended rate during adult resuscitation efforts.
