The Science Behind Circulation When the heart stops, blood no longer circulates, depriving the brain and organs of oxygen. This life-saving technique is essential in situations such as cardiac arrest, drowning, suffocation, or trauma, and knowing how to perform it can mean the difference between life and death.
CPR What Is It Circulation Science Basics
Many organizations, such as the American Heart Association and the Red Cross, offer accessible classes that combine online learning with in-person skills sessions. Cardiopulmonary resuscitation, commonly referred to as CPR, is a critical emergency procedure that combines chest compressions and artificial ventilation to maintain blood flow and oxygenation to the brain and vital organs when a person’s breathing or heartbeat has stopped.
Recognizing When to Use CPR You should initiate CPR if you encounter an unresponsive person who is not breathing normally, or only gasping, and who does not have a pulse. Assessing the scene for safety, checking responsiveness, and activating emergency services are the crucial steps before beginning the physical process of compressions.
CPR What Is It Circulation Science Basics
By pushing on the chest at a specific rate and depth, a rescuer can manually compress the heart, pushing oxygenated blood to the brain and other critical organs. CPR manually circulates a small amount of oxygenated blood through the body, significantly slowing the progression of brain damage.
