Performing chest compressions at a rate of 100 to 120 compressions per minute is the recommended standard during CPR. This rate optimizes blood flow and increases the chances of survival during cardiac arrest. The rate is intentionally set to balance between pushing fast enough to maintain circulation and not so fast that the heart does not adequately refill between compressions. Key points about the compression rate of 100 to 120 per minute:
- It is endorsed by guidelines such as those from the American Heart Association and the American Red Cross for adult CPR.
- Studies have shown that survival and return of spontaneous circulation peak around this rate.
- Compression depth tends to decrease if rates exceed 120, reducing effectiveness.
- Using tools like a metronome or a song (e.g., "Stayin' Alive") helps maintain the correct rhythm.
- The cycle typically consists of 30 compressions followed by 2 rescue breaths.
This rate is crucial in both professional and layperson CPR to maximize the chance of resuscitation success.
