All About CPR

These steps are the American Heart Association's recommendations for providing hands-only CPR. There is growing evidence that this style of CPR is the best for sudden cardiac arrest. In cases of cardiac arrest caused by respiratory issues -- drowning and asthma, for example -- traditional CPR may be a better choice of treatment.

CPR for cardiac arrest patients who've at least reached puberty, defined as breast development or body hair. Use your best judgment to decide whether to use adult or child CPR on those borderline patients.

CPR for children older than 1 year but who haven't reached puberty yet. Small children who are a little older than a year might benefit from infant CPR rather than child CPR.

CPR for kids younger than 1 year. Deciding when to use infant CPR versus child CPR has more to do with the size of the child than the age.

Choking requires a quick response to remove the airway obstruction before it leads to unconsciousness. These steps are for providing the Heimlich maneuver to conscious adults and children aged 1 to 8.

Follow these steps to save a choking infant under 1 year old. Like CPR, choosing whether to perform child or infant choking steps depends on the size rather than age of the child.
