Cardiac Arrest Symptoms and Immediate Response

Recognizing the Signs of Cardiac Arrest

Cardiac arrest is a life-threatening medical emergency that requires immediate attention. One of the most noticeable symptoms is the sudden loss of consciousness, often occurring while the person is engaged in normal activities or during intense physical exertion. Other key indicators include cessation of breathing, absence of pulse, and no response to verbal or physical stimuli. In addition, the person may become unresponsive, fall into a deep coma, have cold extremities, and show no signs of circulation, such as a detectable heartbeat or pulse in the major arteries.

What to Do When Witnessing a Collapse

If you come across someone who has suddenly collapsed and is unresponsive, it's crucial to act quickly. Begin by checking for responsiveness—call out to the person and gently shake them to see if there's any reaction. Next, place your fingers on their wrist or neck to feel for a pulse, lean close to their mouth and nose to check for breathing, and observe the temperature of their limbs. These steps will help you determine whether the person is experiencing cardiac arrest.

Immediate Action Saves Lives

Once cardiac arrest is confirmed, it's essential to start cardiopulmonary resuscitation (CPR) immediately. Time is of the essence, as every second counts in preserving the person's chance of survival. Begin chest compressions and, if trained, provide rescue breaths. If an automated external defibrillator (AED) is available, use it as soon as possible. Prompt action can significantly improve the likelihood of a successful outcome and reduce the risk of long-term complications.
