Cardiac arrest is a life-threatening emergency that requires immediate intervention. One of the most critical factors in successful resuscitation is the rate at which chest compressions are performed. The compression rate —measured in compressions per minute—plays a crucial role in restoring circulation, improving survival rates, and enhancing neurological outcomes. Understanding how compression rates affect cardiac arrest outcomes is essential for healthcare providers, emergency responders, and even bystanders trained in CPR. This article will explore the science behind compression rates, their impact on patient survival, and best practices for effective chest compressions. Understanding Compression Rates in Cardiac Arrest What Is a Compression Rate? A compression rate refers to the speed at which chest compressions are delivered during Cardiopulmonary Resuscitation (CPR) . The American Heart Association (AHA) recommends a compression rate of 100–120 compressions per minute (c...
