Straight arms help to drive body weight downwards with enough power to reach the proper compression depth with the least energy expelled. If arms are bent during chest compressions, the muscles must work much harder to administer the same force, and the first aider is likely to tire quickly. Keep your hands interlocked and in the center of the chest wall while avoiding leaning onto the victim.
It occurs when the rescuer’s hands don’t remain in contact with the victim’s chest. Non-trained individuals should focus on compression-only CPR, and trained first aiders should stick to the 30:2 compression to breaths rule. Rescue breaths are considered secondary (and optional for lay responders). Now, much more emphasis is put on chest compressions.
In recent years, the guidelines around rescue breaths during CPR have changed. Excessive ventilation when giving rescue breaths If a first aider leans on the victim’s chest, recoil and expansion are diminished, which could have fatal consequences. This recoiling action pulls lifesaving blood back into the heart. When performing high-quality CPR, the victim’s chest must be allowed to recoil and expand between each compression fully. Common CPR Mistakesīy pausing between compressions or delivering compressions at too slow a rate, the victim’s organs will become starved of oxygen and die.Īdministering 100 to 120 compressions per minute is much faster than many think, a little less than two every second. Healthcare providers studies show that the majority of cardiac arrest victims sustain at least one rib fracture. This is often unavoidable and you should not stop performing continuous chest compressions.Įnsure your hands are in the correct position and continue delivering high quality CPR until emergency medical services (EMS) take over. You may feel a victim’s ribs break when performing high-quality CPR. Each compression and release should take an equal amount of time.Repeat at a rate of 100 – 120 chest compressions per minute.After each compression, release all the pressure on the chest without losing contact between your hands and the sternum.Position yourself vertically above the victim’s chest and, with your arms straight, press down on the sternum approximately 5 – 6 cm.Do not apply any pressure over the upper abdomen or the bottom end of the sternum Interlock the fingers of your hands and ensure that pressure is not applied to the victim’s ribs.Place the heel of your other hand on top of the first hand.Place the heel of one hand in the center of the victim’s chest.To achieve a high chest compression fraction, follow these steps: Performing High-Quality Chest Compressions Excessive ventilation (delivering too many breaths) lowers the chest compression fraction and reduces the chance of survival during cardiac arrest. Avoid excessive ventilation: maintain two breaths for every 30 compressions.Ensure that the time spent compressing the chest matches the length of time enabling the chest to recoil and expand. Avoid leaning on the chest in between compressions.Chest compression depth: between 2-2.4 inches (5-6 cm) for adults and adolescents, 2 inches (5cm) for prepubescent children, and 1.5 inches (4cm) for infants.The AHA even has a playlist, ‘ Don’t Drop the Beat,’ featuring specially chosen tracks that match the ideal 100 –120 bpm chest compression rate. It’s the optimum rate needed to give the patient the highest chance of survival. Chest compression rate: between 100-120 compressions per minute.It’s the proportion of time a first aider spends performing chest compressions during CPR. In 2020, the American Heart Association (AHA) and the European Resuscitation Council (ERC) updated their guidelines to outline the five crucial components of high-quality CPR. In addition, performing rescue breaths may put off bystanders from intervening and beginning vital CPR. Hands-only CPR is now being taught to laypeople as it is recognized that rescue breaths are not as important in the initial few minutes after a cardiac arrest.

High quality CPR involves rescuers being aware of how to deliver effective chest compressions to a victim in order to improve the chances of a successful defibrillation. Effective chest compressions are the most important component of Cardiopulmonary Resuscitation (CPR).
