When someone is in cardiac arrest, usually the blood oxygen levels are sufficient for at least 3-5 minutes, and perhaps longer. If you give rescue breaths, any pause you make for delivering them should be as short as possible, bearing in mind that according to the AHA each rescue breath should last 1 second. That means you are spending 60% or more of the time delivering compressions. The AHA recommends a CCF of at least 60%. Chest Compression Fraction, Rescue Breathing, and PausesĬhest compression fraction (CCF) is the proportion of CPR time spent providing compressions during a cardiac arrest event. When performing CPR, you need to minimize any pauses in chest compressions to have adequate CCF. When doing CPR, focus on getting the compressions down to the correct depth. For prepubescent children and babies, the compression depth should be 1.5 inches (4 cm) in infants to 2 inches (5 cm) in children. Leaning on the chest should be avoided between each compression.Ī person performing CPR should compress the adult victim’s chest to at least two inches, but no more than 2.4 inches. When delivering compressions, the amount of time you spend compressing the chest and allowing it to recoil should, ideally, be equal. The American Heart Association has developed a playlist to help people remember the correct rate for chest compressions, by using the beat of a familiar song! All of the songs in this playlist are between 100–120 beats per minute. Rates above or below this range reduce the chances of survival of the victim. The recommended compression rate for high-quality CPR is between 100 and 120 compressions per minute. Ideally, you will perform CPR on a firm surface and the victim will be on their back. If you can perform CPR safely where the victim is found, do not move the victim. Fold your other hand over the top, interlacing your fingers to create a good grip. You should place the heel of one of your hands in the middle of the victim’s chest toward the bottom third of their sternum. Safe, Supportive Positioning and Locationĭuring CPR, your hands must be placed appropriately to ensure accurate and safe chest compressions. These guidelines offer four main metrics to meet to ensure the CPR you give to adult victims is as safe and effective as possible.

In 2020, based on updates to the international CPR guidelines, the AHA released updated guidelines on how to deliver high-quality CPR to adults.
