Every parent should know how and when to administer CPR. When performed correctly, CPR can save a child's life by restoring breathing and circulation until advanced life support can be given by health care providers.

About CPR

CPR (or cardiopulmonary resuscitation) is a combination of rescue breathing (mouth-to-mouth resuscitation) and chest compressions. If someone isn't breathing or circulating blood adequately, CPR can restore circulation of oxygen-rich blood to the brain. Without oxygen, permanent brain damage or death can occur in less than 8 minutes.

CPR may be necessary during many different emergencies, including accidents, near-drowning, suffocation, poisoning, smoke inhalation, electrocution injuries, and suspected sudden infant death syndrome (SIDS).

Reading about CPR and learning when it's needed will give you a basic understanding of the concept and procedure, but it's strongly recommended that you learn the details of how to perform CPR by taking a course. If CPR is needed, using the correct technique will give someone the best chance of recovery.

CPR is most successful when administered as quickly as possible, but you must first determine if it's necessary. It should only be performed when a person isn't breathing or circulating blood adequately.

First, determine that it's safe to approach the person in trouble. For instance, if someone was injured in an accident on a busy highway, you'd have to be extremely careful about ongoing traffic as you try to help. Or if someone touched an exposed wire and was electrocuted, you'd have to be certain that he or she is no longer in contact with electricity before offering assistance to prevent becoming electrocuted yourself. (For instance, turn off the source of electricity, such as a light switch or a circuit breaker.)

Once you know that you can safely approach someone who needs help, quickly evaluate whether the person is responsive. Look for things such as eye opening, sounds from the mouth, or other signs of life like movement of the arms and legs. In infants and younger kids, rubbing the chest (over the breastbone) can help determine if there is any level of responsiveness. In older kids and adults, this also can be done by gently shaking the shoulders and asking if they're all right.

The next step is to check if the victim is breathing. You can determine this by watching the person's chest for the rise and fall of breaths and listening for the sound of air going in and out of mouth or nose. In a CPR or basic life support (BLS) course, participants practice techniques for determining if breathing or circulation is adequate. If you can't determine whether someone is breathing, you should begin CPR and continue until help arrives.

Whenever CPR is needed, remember to call for emergency medical assistance. Current CPR courses teach you that if you are alone with an unresponsive infant or child, give chest compressions for five cycles (about 2 minutes) before calling for help.

Three Parts of CPR

The three basic parts of CPR are easily remembered as "ABC": A for airway, B for breathing, and C for circulation.

  1. A is for airway. The victim's airway must be open for breathing to be restored. The airway may be blocked when someone loses consciousness or may be obstructed by food or another foreign object. In a CPR course, participants learn how to open the airway and position the person so the airway is ready for rescue breathing. The course will include what to do to clear the airway if you believe an infant or child has choked and the airway is blocked.
  2. B is for breathing. Rescue breathing is begun when a person isn't breathing. Someone performing rescue breathing essentially breathes for the victim by forcing air into the lungs. This procedure includes breathing into the victim's mouth at correct intervals and checking for signs of life. A CPR course will review correct techniques and procedures for rescuers to position themselves to give mouth-to-mouth resuscitation to infants, kids, and adults.
  3. C is for circulation. Chest compressions can sometimes restore circulation. Two rescue breaths should be provided, followed immediately by 30 chest compressions. This cycle of two rescue breaths and 30 chest compressions is repeated five times in an infant or child with an unwitnessed collapse prior to calling for help. This cycle is immediately resumed and continued until the child recovers or help arrives. It is not necessary to check for signs of circulation to perform this technique. This procedure involves pushing on the chest to help circulate blood and maintain blood flow to major organs. A CPR course will teach you how to perform chest compressions in infants, kids, and adults, and how to coordinate the compressions with rescue breathing.

Taking a CPR Course

Nearby hospitals and your local chapters of the American Heart Association (AHA) and the American Red Cross are good sources for finding a CPR course in your area.

Qualified instructors may use videos, printed materials, and demonstrations on mannequins representing infants, children, and adults to teach proper techniques for performing CPR.

The AHA's basic life support course that includes CPR lasts about 3 hours and takes place within one session. The course covers adult, child, and infant CPR and choking. Participants practice the techniques on mannequins and can ask questions and get individualized instruction. The final test for the course is a combination of demonstrating CPR skills and taking a written test.

Because CPR is a skill that must be practiced, it's wise to repeat the course at least every 2 years to maintain your skills. Doing so also allows you to learn about any new advances or discoveries in CPR techniques.

Remember, taking a CPR course could help you save your child's — or someone else's — life someday.
