ADULT CHEST COMPRESSIONS

The universal rate for compressions in all cardiac arrest victims (adult, child, or infant) is 100 to 120 per minute. Likewise, the compressions-to-ventilation ratio for 1 rescuer (30:2) is the same for adult, child, and infant victims. For 2 rescuers, the compressions-to-ventilation ratio for adult, child or infant is 15:2.

When you give chest compressions:

  • compress, rapidly, at a rate of 100 to 120 compressions per minute
  • compress the chest hard, at least 2 inches (5 cm)
  • allow the chest to recoil fully after each compression
  • minimize interruptions in compressions

Do not move victim unless he is face down, appears to be in imminent danger, or on a soft or otherwise unsuitable surface such as a bed or bathtub.

Performing chest compressions:

  1. the victim must be face up on a firm, flat surface. If you must move or roll them over, be extremely careful if you suspect head or neck injury
  2. stand or kneel at the victim’s side
  3. position your hands and body to perform chest compressions:
    • place the heel of one hand in the center of the victim’s chest, on the lower half of the breastbone (sternum)
    • place the heel of your other hand on top of the first hand
    • straighten your arms and position your shoulders directly over your hands
  4. begin chest compressions at a rate of 100 to 120 per minute
  5. press fast and hard, at least 2 inches (5 cm) making sure you push straight down on the victim’s breastbone
  6. at the end of each compression, allow the chest to recoil completely
