What is a common intervention during a cardiac arrest?

During a cardiac arrest, the primary objective is to restore effective circulation and oxygenation to vital organs, particularly the brain and heart. Initiating cardiopulmonary resuscitation (CPR) is a critical intervention as it helps maintain blood flow to the brain and other organs until advanced medical help can take over. CPR involves chest compressions and rescue breaths, which keep oxygenated blood circulating temporarily.

Defibrillation is also a vital component of treating certain types of cardiac arrest, particularly those caused by arrhythmias like ventricular fibrillation or pulseless ventricular tachycardia. The use of an automated external defibrillator (AED), if available, can significantly increase the chances of survival if applied promptly and effectively.

While other interventions are important in their respective scenarios, they do not directly address the immediate needs of a patient in cardiac arrest. For example, applying a tourniquet is used in cases of severe bleeding, not cardiac arrest. Heat packs might be applied for hypothermia or pain relief but have no role during a cardiac arrest. Positioning a patient upright may be suitable for other conditions but would not be appropriate for someone experiencing cardiac arrest, where the goal is to maintain blood flow rather than facilitate an upright position.
