Once you have quickly assessed the situation and checked the consciousness and circulation of the victim you need to act very quickly. If there is no pulse you must begin CPR immediately, and continue it for two minutes (which is about five cycles of CPR) and then call for Emergency Medical Services. If you are alone it is important to start CPR before calling for help.  If someone else is there send them for help. If you are alone, do not call until you have completed two minutes of CPR.   Dial your local emergency number. Call 911 in North America, 000 in Australia, 111 in New Zealand, 112 by cell phone in the EU (including the UK) and 999 in the UK. If possible, send someone else to get an AED (Automatic External Defibrillator) if there is one in the building or nearby. CAB is the basic process of CPR. It stands for Chest Compressions, Airway, Breathing. In 2010, the recommended sequence changed with chest compressions placed before airway opening and rescue breathing. Chest compressions are more critical for correcting abnormal heart rhythms (ventricular fibrillation or pulseless ventricular tachycardia), and because one cycle of 30 chest compressions only requires 18 seconds, airway opening and rescue breathing are not significantly delayed. Chest compressions, or hands-only CPR is recommended if you have not been properly trained or are worried about performing mouth-to-mouth resuscitation on a stranger. When performing CPR on a child the positioning of your hands is especially important, given that a child will be more fragile than an adult. Locate the child's sternum by moving two fingers to the bottom of the rib cage. Identify where the lower the ribs meet in the middle and then place the heel of your other hand on top of your fingers. Just use the heel of this hand to do the compressions. Compress the chest, with elbows locked, by pushing straight down about 2 inches (5.1 cm) deep. The smaller body of a child needs less pressure than an adult would. If you begin to hear or feel a cracking sound,...

TL;DR in Indonesian:
Lakukan RJP selama 2 menit. Ingatlah CAB. Posisikan tangan untuk melakukan kompresi. Lakukan 30 kali kompresi. Pastikan jalur pernapasan terbuka. Berikan dua kali bantuan napas. Ulangi siklus kompresi dada sebanyak 30 kali dan dua bantuan napas. Gunakan AED.
