CPR and AED:
Cardiac arrest is a life-threatening condition, but quick action can make a significant difference in saving a life. Every year, nearly 90% of cardiac arrests that occur outside of the hospital result in death. However, studies show that performing CPR (cardiopulmonary resuscitation) and using an AED (automated external defibrillator) can increase the chances of survival, often doubling or even tripling them.
Michelle Gossip, a cardiology nurse at VCU Health Pauley Heart Center, has experienced firsthand how important it is to act quickly during heart emergencies. She has performed CPR on two individuals in the community and believes that even if you’re unsure about your technique, any action is better than doing nothing. “Trust your training and instincts,” she says. “You can save a life by stepping up in the moment.”
A heart attack occurs when a coronary artery is blocked, leading to chest pain, arm or jaw discomfort, and shortness of breath. In contrast, a cardiac arrest happens when the heart stops beating completely. The person becomes unresponsive, their skin may turn blue or gray, and they stop breathing normally. Time is critical in a cardiac arrest — the sooner you act, the better the chance of survival.
CPR helps to keep oxygen-rich blood flowing to vital organs until emergency medical personnel arrive. By applying deep chest compressions, you essentially “pump” the heart manually. Hands-only CPR, which involves just chest compressions without mouth-to-mouth breathing, is recommended for people who might feel uncomfortable with the breathing component. Aim for compressions that are about 1.5 to 2 inches deep at a rate of 100 to 120 per minute.
An AED is a portable device that can analyze the heart’s rhythm and deliver a shock if necessary. It is user-friendly and provides clear voice prompts to guide anyone, even without medical training, through the process. It is important to know where AEDs are located in public places or workplaces, as they can be life-saving during an emergency.
If someone is unresponsive, check for normal breathing and call 911 immediately. If an AED is available, get it right away and start CPR. If you’re alone, use your phone to contact emergency services and begin chest compressions.
In any heart emergency, your actions can be the difference between life and death. Even imperfect CPR and the use of an AED can drastically improve survival chances.
