  • Crawl up the rib-cage using both hands
  • The notch where your two hands meet is the xiphoid process
  • Place the heel of your hand two finger widths above the xiphoid process - on the sternum
  • Interlock your two hands and push down 1.5-2 inches (4-5 cm) on the sternum
  • Compress 30 times then give 2 breaths (this is 1 cycle)
  • Recheck the pulse after 1 minute (equivalent to approx. 6 cycles)
    Lay rescuers should no longer interrupt CPR to check the pulse
  • Continue CPR until help arrives, an AED arrives, or the victim begins to move


If Automatic External Defibrillator arrives attach it to the victim

Each compression should be faster than 1 second. PUSH HARD, PUSH FAST. Aim for 100 compressions/minute. Make sure to allow complete chest recoil after each compression.

If you are doing 2-person CPR on an adult, one person does the chest compressions, while the other gives the breaths. The ratio of compressions to breaths is still 30:2. Take turns after performing a few minutes of compressions.

If you do not have a facemask or other physical barrier and feel uncomfortable giving mouth-to-mouth breaths, you may do chest compressions without ventilations.
