What is CPR according to 2010 guidelines?

Cardiopulmonary resuscitation (CPR) is a lifesaving technique that is performed on a person who has stopped breathing or whose heart has stopped beating. It is important to start CPR as soon as possible, as the chances of survival decrease rapidly with each passing minute.

The 2010 CPR guidelines recommend the following steps:

1. Check for responsiveness. Gently shake and shout to the person, "Are you okay?" If the person is unresponsive, call 911 or the local emergency number.

2. Start chest compressions.

- Position the heel of one hand on the center of the person's chest, between the nipples.

- Place your other hand over the first hand and interlock your fingers.

- Give 30 chest compressions at a rate of 100 to 120 per minute.

- Push down 3.8 to 5 centimeters (1.5 to 2 inches) on the chest and allow it to recoil between compressions.

- Avoid bending your elbows.

- Keep the pressure on the chest throughout the compression and do not lift your hands.

3. Give rescue breaths.

- After 30 chest compressions, give two rescue breaths.

- Pinch the person's nose closed and cover their entire mouth with your mouth.

- Give a breath that makes the chest rise visibly.

- Allow air to exit before giving the next breath.

4. Continue CPR until help arrives.

- Continue cycles of 30 chest compressions and two rescue breaths until help arrives.

- If you become tired, have someone else take over compressions.

- Do not stop CPR unless the person starts breathing or a healthcare provider tells you to stop.

5. Use an automated external defibrillator (AED) if available.

- If an AED is available, turn it on and follow the voice prompts to deliver a shock.

- Continue CPR until the AED is ready to deliver another shock or until help arrives.

By following these steps, you can help save the life of someone who has suffered a cardiac arrest.
