2. Call 9-1-1 (or emergency medical services): After ensuring the scene is safe, you should immediately call for professional help. In most countries, dialing 9-1-1 will connect you to emergency services.

3. Start CPR: Once you have called for help, it is important to begin chest compressions as soon as possible. Place the heel of one hand on the center of the person's chest (between the nipples), and place the other hand on top of the first hand. Use your body weight to push hard and fast in the center of the chest, aiming for a rate of 100 to 120 compressions per minute.

4. Stop after the paramedics arrive: You should continue performing CPR until trained medical professionals such as paramedics arrive on the scene. Paramedics are specifically trained and equipped to provide advanced medical care, so it is important to allow them to take over once they arrive.

Based on the given options, the correct sequence is: check the scene; call 9-1-1; start CPR; stop after the paramedics arrive.
