During CPR on an adult who is unresponsive and not breathing normally, at what rate should chest compressions be given?

Correct answer

Between 100 and 120 compressions per minute.

Between 100 and 120 compressions per minute. Call emergency services promptly for an unresponsive person and follow instructions; start CPR if breathing is abnormal. Compress the centre of the chest 5–6 cm and allow full recoil, minimising interruptions. If trained and able to provide breaths, alternate 30 compressions with 2 breaths; otherwise provide continuous compressions following instructions. This is the rate while compressing, not a requirement to complete exactly 100 in every elapsed minute including pauses.
