What is the correct compression rate for CPR?

Push at 100–120 compressions per minute (AHA guidelines). A useful memory aid: the beat of 'Stayin' Alive' by the Bee Gees is approximately 103 BPM — matching the recommended CPR rate.

How deep should chest compressions be?

For adults, compress at least 2 inches (5 cm) deep, but no more than 2.4 inches (6 cm). For children, compress about 2 inches (5 cm). For infants, compress about 1.5 inches (4 cm) using two fingers.

Should bystanders give rescue breaths during CPR?

For untrained bystanders, Hands-Only CPR (compression-only, no rescue breaths) is recommended for witnessed adult cardiac arrest. This is equally effective in the first few minutes and more likely to be performed correctly. If trained, you may give 2 rescue breaths every 30 compressions.
