Cardiopulmonary Resuscitation (CPR) (cont.)
Start with Chest Compressions
- If the person is not breathing normally, begin doing chest compressions. Place the heel of one hand on the center of the chest, right between the nipples. Place the heel of your other hand on top of the first hand. Lock your elbows and position your shoulders directly above your hands. Press down on the chest with enough force to move the breastbone down about 2 inches. Compress the chest 30 times, at a rate of at least 100 times per minute (slightly faster than once every second). Allow the chest to completely recoil after each compression.
- The 2015 CPR recommendations for bystanders states that untrained bystanders should perform compression-only CPR (Hands-Only CPR). Bystanders trained in CPR who can perform breaths should do so in a cycle of 30 compressions and two breaths as decribed above.
- The chest compression rate and depth were updated in 2015. In adult victims of cardiac arrest, it is reasonable for rescuers to perform chest compressions at a rate of 100 to 120 compressions per minute to a depth of at least 2 inches for an average adult, while avoiding excessive chest compression depths of greater than 2.4 inches.
