What is a common treatment step for a patient experiencing cardiac arrest?

Immediate cardiopulmonary resuscitation (CPR) is a critical and common treatment step for a patient experiencing cardiac arrest because it helps maintain blood flow to vital organs in the absence of effective heart function. When the heart stops beating, there is no circulation of blood, leading to a rapid decline in oxygen delivery to the brain and other essential organs. By performing CPR, specifically chest compressions, the practitioner can artificially circulate blood and provide a chance for the heart to restart or for defibrillation to be effective.

CPR is a foundational emergency response that can significantly improve outcomes for cardiac arrest victims, as it buys time until advanced medical help arrives or an Automated External Defibrillator (AED) can be utilized. This action not only aids in maintaining organ viability but also increases the likelihood of return of spontaneous circulation (ROSC) upon defibrillation or advanced interventions.

The other approaches, such as administering sedatives or transporting the patient without assessment, would not address the immediate life-threatening situation of cardiac arrest. Waiting for further instructions without intervening could lead to irreversible damage or death. Therefore, immediate initiation of CPR is essential in these scenarios.
