Final answer:
The ARC commonly recommends the use of 100% oxygen during cardiac arrest situations, and while drugs may be used per advanced life support guidelines, AEDs and CPR are crucial for immediate intervention in public places.
Step-by-step explanation:
The student question addresses a medical protocol issue, specifically what is recommended in cardiac arrest situations by the American Red Cross (ARC). Drugs such as amiodarone, magnesium, sodium bicarbonate, and vasopressin are used in advanced life support algorithms, depending on the specifics of the cardiac arrest. However, 100% oxygen is commonly and routinely administered during resuscitative efforts until the patient's own breathing is adequate.
Automated external defibrillators (AEDs) are critical in providing an electrical shock, or defibrillation, to help the heart regain a proper rhythm. These devices are designed for use by both medical professionals and laypeople in public places and during emergency situations. Additionally, during cardiac emergencies, especially in out-of-hospital settings, CPR (cardiopulmonary resuscitation) is highly recommended prior to the use of an AED.
