5 Steps to Start CPR
Short answer
Starting CPR requires five clear steps: first, ensure the scene is safe; second, check if the person is responsive and breathing; third, call 911 or emergency services; fourth, begin chest compressions; and fifth, provide rescue breaths if trained. These steps keep oxygen flowing through the body until professional help arrives, greatly increasing chances of survival.
What is CPR in simple terms?
CPR, or cardiopulmonary resuscitation, is an emergency life-saving technique performed when someone's heart or breathing stops. It involves manually pressing on the chest to keep blood circulating and, in some cases, providing breaths to supply oxygen. Think of it as a way to temporarily take over the heart and lung functions to maintain vital organ health, especially the brain, until emergency medical personnel arrive.
The process is designed so that almost anyone can perform it with minimal training, using hands-only CPR or full CPR with rescue breaths. It's not a medical treatment but a critical first response that buys time. By pushing on the chest, you squeeze the heart between the breastbone and spine, helping blood flow through the body. If rescue breaths are given, they add oxygen to the lungs, which is necessary for the blood to carry oxygen to organs.
Understanding CPR in these simple terms helps remove fear or confusion, making it more likely for someone to act during an emergency. It saves lives by providing immediate support when every second counts.
How does CPR work with a clear example?
Imagine walking in a grocery store when a person near you suddenly falls to the floor and doesn’t respond. You quickly kneel beside them and check if they are breathing normally. They only gasp, so you know it’s not normal. You call 911 on your phone or ask someone nearby to do it. Without hesitation, you place the heel of your hand on the center of their chest and push hard and fast, about 2 inches deep at a rate of 100 to 120 compressions per minute. After 30 compressions, if trained, you tilt the person’s head back slightly, pinch their nose, and give 2 rescue breaths, watching for their chest to rise.
By doing this, you are manually pumping their heart and supplying oxygen to their brain, which can keep their organs alive and reduce brain damage risk until paramedics arrive. For example, if you press down for about one second and release for one second repeatedly, you maintain a steady rhythm that maximizes blood flow.
This hands-on example shows how CPR works as a life-saving bridge during cardiac arrest or respiratory failure, making a dramatic difference in survival chances.
Why does learning these 5 steps matter for everyone?
Cardiac arrest can strike anyone—young or old, healthy or sick—without warning. Knowing the five steps to start CPR means being prepared to act immediately, which can double or triple a person’s chances of survival. The brain begins to suffer serious damage within minutes of oxygen loss, so delays in response can lead to permanent disability or death.
Many people hesitate to help because they don’t know what to do or fear making mistakes. Learning these steps builds confidence, reduces hesitation, and encourages bystanders to help rather than stand by. It also lowers the chances of panic, which can waste precious time.
Since emergency medical services may take several minutes to arrive, your immediate action with CPR is vital. This knowledge is essential not only for adults but for teens, parents, teachers, and anyone who wants to be prepared. Having more people trained makes communities safer overall.
What are some related terms people confuse with CPR?
It’s common to confuse CPR with other emergency procedures or terms:
- First aid: This is a broad term covering many emergency treatments like bandaging wounds, treating burns, or stopping bleeding. CPR is a specific type of first aid used when the heart or breathing stops.
- Heimlich maneuver (abdominal thrusts): This procedure is used to relieve choking by forcing an object out of the airway. It’s different from CPR, which is done when a person is unresponsive and not breathing.
- Defibrillation: This involves using an Automated External Defibrillator (AED) to deliver an electric shock to restart the heart. CPR is performed manually and usually starts before an AED is available.
- Rescue breathing: This is giving breaths to someone who is not breathing but still has a pulse. CPR combines rescue breathing and chest compressions when there is no pulse.
Understanding these differences helps you respond correctly during emergencies. For example, if a person is choking but conscious, perform the Heimlich maneuver; if unconscious and not breathing, start CPR immediately.
What are the 5 exact steps to start CPR?
When you encounter someone who may need CPR, follow this step-by-step process. Practice this exact wording and actions to stay calm and effective:
- Check the scene for safety. Look around to make sure the environment is safe for you and the victim — no traffic, fire, electrical hazards, or unstable surfaces. Say aloud, “Is it safe for me to help you?”
- Check responsiveness and breathing. Gently tap the person’s shoulder and shout, “Are you okay?” Look for normal breathing (not gasping or irregular). If they don’t respond and aren’t breathing normally, CPR is needed.
- Call 911 or emergency services immediately. If possible, put the phone on speaker mode and say, “Help! A person is unresponsive and not breathing normally. I’m starting CPR.” If someone else is nearby, ask them to call while you begin CPR.
- Start chest compressions. Place the heel of one hand on the center of the chest (on the lower half of the breastbone). Put your other hand on top, interlock your fingers. Keep your arms straight and shoulders above your hands. Push hard and fast—compress at least 2 inches deep and at a speed of 100 to 120 compressions per minute (about the beat of “Stayin’ Alive” by the Bee Gees). Let the chest fully recoil between compressions.
- Give rescue breaths if trained. After 30 compressions, open the airway by tilting the head back and lifting the chin. Pinch the nose shut, take a normal breath, and make a complete seal over the person’s mouth. Blow steadily into their mouth for about 1 second so the chest rises visibly. Repeat for a second breath, then resume compressions.
Continue this cycle (30 compressions, 2 breaths) until emergency responders arrive, the person starts breathing, or you are too exhausted to continue. If you are not trained or hesitant about breaths, doing chest compressions alone is still highly effective.
What should you do next after learning these steps?
Taking a CPR certification course from a recognized organization like the American Red Cross or American Heart Association is the best next step. These courses provide hands-on practice, feedback, and confidence boosting. Expect to spend a few hours learning and practicing chest compressions, rescue breaths, and AED use.
Keep your certification current by retaking the course every two years or as required. Review the steps regularly to keep skills fresh. Consider teaching friends or family so more people around you can respond in emergencies.
Also, learn how to use an AED, which can often be found in public spaces like malls, airports, and schools. Using an AED with CPR increases survival chances even more.
Finally, stay calm and remember the five steps. Your preparedness can make the vital difference between life and death.

Frequently asked questions
How deep should chest compressions be during CPR?
Chest compressions for adults should be about 2 inches deep. This depth helps create enough pressure to pump blood effectively. Make sure to allow the chest to fully rise back between compressions for maximum blood flow.
Can CPR cause injury to the person?
CPR can sometimes cause bruises or broken ribs because of the force needed. However, this risk is minor compared to the benefit of saving a life during cardiac arrest. It is better to perform CPR than to do nothing.
What if I’m alone and need to perform CPR?
If you are alone, call 911 first if possible before starting CPR. If you cannot call immediately, start CPR for about 2 minutes, then call emergency services if no one else can help.
Should I perform rescue breaths if I’m not trained?
If not trained or uncomfortable with rescue breaths, perform hands-only CPR by doing continuous chest compressions. This is still effective in keeping blood circulating until help arrives.
How does CPR differ for children or infants?
For children, compress about 2 inches deep (a third of the chest depth) and use one or two hands depending on size. For infants, use two fingers for compressions about 1.5 inches deep. Rescue breaths are also gentler. Specialized training is recommended.
