As an expert in emergency medical response, I would like to guide you through the process of performing Cardiopulmonary Resuscitation (CPR) on an adult. CPR is a critical life-saving technique that can maintain blood flow to vital organs when someone's heart has stopped beating. It's important to act quickly and effectively in an emergency situation.

Step 1: Assess the Scene
Before you start CPR, ensure the scene is safe for both you and the victim. Look for any potential hazards such as traffic, fire, or electrical dangers.

Step 2: Check for Responsiveness
Gently tap the person's shoulder and ask loudly, "Are you okay?" If there is no response, proceed to the next step.

Step 3: Call for Help
If someone else is nearby, have them call emergency services immediately. If you are alone, you will need to call 911 or your local emergency number yourself.

Step 4: Open the Airway
Tilt the person's head back slightly by lifting the chin and check for breathing. If the person is not breathing or is gasping for air, begin CPR.

Step 5: Begin Chest Compressions
Place the heel of your hand on the center of the person's chest. This is typically at the lower half of the breastbone, or sternum. Place your other hand on top of the first and interlock your fingers to ensure they do not press into the person's chest.

Step 6: Perform Compressions
Press down by 5-6cm (2-2.5 inches) at a steady rate of 100 to 120 compressions per minute. Allow the chest to fully recoil between compressions. The force should be strong enough to move the heart and create blood flow.

Step 7: Rescue Breaths
After every 30 chest compressions, give two rescue breaths. To do this, pinch the person's nose shut, take a normal breath, and then create a seal over the person's mouth with your mouth. Give a breath that lasts about one second. Watch for the chest to rise and fall.

Step 8: Continue CPR
Continue this cycle of 30 compressions followed by two breaths until help arrives, the person starts to breathe on their own, or you are too exhausted to continue.

Step 9: Use an AED if Available
If an Automated External Defibrillator (AED) is available, turn it on and follow the voice prompts. An AED can shock the heart back into a normal rhythm if an abnormal heart rhythm is detected.

Step 10: Post-CPR Care
Once medical help arrives or the person starts to show signs of life, provide any necessary post-CPR care. This may include turning the person onto their side to prevent aspiration if they start vomiting.

Remember, the key to successful CPR is to act quickly and perform the technique correctly. It's also important to receive proper training to ensure you are prepared to respond in an emergency.
