What is one of the first actions to take when someone is in cardiac arrest?

When someone is in cardiac arrest, one of the first and most crucial actions to take is to contact emergency medical services (EMS). This step is essential because cardiac arrest is a life-threatening emergency that requires immediate medical intervention. Calling EMS ensures that trained professionals are on their way to provide advanced care, which may include defibrillation, medication, and other life-saving measures.

While checking for a pulse is important in assessing the situation, if cardiac arrest is suspected, action needs to be taken quickly to initiate help. Administering medication should only be done under the guidance of medical professionals and is not appropriate for bystanders or laypersons at the scene. Raising the legs may be suggested in certain situations to improve blood flow but is not a priority action in the context of cardiac arrest.

By focusing on contacting EMS, you help ensure that the individual receives the necessary care as quickly as possible, significantly increasing their chances of survival.
