CPR (cardiopulmonary resuscitation) combines chest compressions and rescue breaths to keep blood and oxygen moving during sudden cardiac arrest.
Hands-Only CPR
Hands-only CPR has two steps: call 911 and push hard and fast in the center of the chest at 100–120 BPM until help arrives. No breaths required.
AED Training
AED training teaches you to power on the device, attach pads, follow voice prompts, and deliver a shock safely. Most CPR courses include AED instruction.
Choking Response
For a conscious choking adult or child, use 5 back blows and 5 abdominal thrusts. If the person becomes unresponsive, start CPR immediately.
