[Cardiopulmonary arrest].

Cardiopulmonary arrest is an acute emergency characterized by the absence of central pulse and ventilatory movements. Only the fast intervention of a resuscitation unit allows in some cases to preserve the vital prognostic. However its action can be efficient only if resuscitation gestures have been undertaken as soon as the cardiopulmonary arrest is established by the practitioner. These gestures are chest compressions and artificial ventilation. Their efficiency can be increased by the use of a simple and inexpensive oxygen therapy equipment.
