[Definitions and prevention of cardiorespiratory arrest in children].

In cardiopulmonary resuscitation ages are divided in neonates (in the inmediate period after the birth), infant (from birth to 12 months) and child (from 12 months to puberty). Respiratory arrest is defined by the absence of spontaneous respiration (apnea) or a severe respiratory insufficiency (agonal gasping) that require respiratory assistance. Cardiac arrest is defined as the absence of central arterial pulse or signs of circulation (movement, cough or normal breathing) or the presence of a central pulse less than 60 lpm in a child who does not respond, not breath and with poor perfusion. After resuscitation the return of spontaneous circulation is defined as the recuperation of central arterial pulse or signs of circulation in a child with previous cardiorespiratory arrest. It is maintained when the duration is longer than 20 minutes. Injuries, sudden infant death syndrome, and respiratory diseases are the most frequent etiologies of cardiorrespiratory arrest in children. The prevention and the formation of citizens in basic cardiopulmonary resuscitation are the most effective measures to reduce the mortality of cardiorespiratory arrest in children.
