Who Can Use an AED?

Who can use an automated external defibrillator (AED)? You can. Who should use an AED? You should.

AEDs are designed to be used by non-medical personnel, such as firefighters, police officers, lifeguards, flight attendants, security guards, teachers, family members of high-risk persons, and bystanders. That includes you!

Anyone can use (and should use) an AED in the event of sudden cardiac arrest (SCA). The goal of AEDs and public access defibrillation programs ensure access to defibrillation when needed as quickly as possible. CPR along with AEDs can dramatically increase survival rates for sudden cardiac arrest. 

Although formal training in the use of an AED is not required, AED and CPR certifications are recommended to help you increase your comfort and level of confidence. However, AEDs are intended for use by the general public — with or without specialized training.

What is an AED and How Does It Work?

What is an AED and how does it work? An AED is a lightweight, portable device that delivers an electric shock through the chest wall to the heart. The shock can potentially stop an irregular heartbeat (arrhythmia) and allow a normal heart rhythm to resume following cardiac arrest. 

SCA occurs when the heart malfunctions and stops beating unexpectedly. If not treated within minutes, it quickly leads to death.

AEDs can be used by non-medical personnel — which includes lay rescuers and bystanders just like you! Once the AED electrodes are attached to the victim’s chest, the device automatically checks and analyzes a victim’s heart rhythm. The device calculates whether defibrillation is needed. If it is, a recorded voice prompts the rescuer to press the shock button on the AED or, depending on the model, automatically delivers the shock. 

The shock effectively stuns the heart and stops all activity, giving the heart a chance to resume a normal heart rhythm. Audio and text prompts — depending on the model — guide the user through the process of administering shock or performing CPR. AEDs advise a shock only when absolutely necessary. 

Where Can I Find an AED?

Potential rescuers should look for AEDs in public areas such as sports venues, community centers, shopping malls, casinos, amusement parks, airports, airplanes, businesses, convention centers, hotels, schools, and doctors’ offices. 

Finding the best location for an AED takes some thought and consideration. Often, however, they can be found in highly trafficked areas in well-marked and accessible wall cabinets. Popular locations include hallways, main corridors, near elevators, cafeterias, or main reception areas.

Why is CPR so Important if I have an AED?

AEDs are designed to shock a heart back into a normal rhythm. They aren’t designed to keep blood flowing to critical organs. CPR, or cardiopulmonary resuscitation, is an easy-to-learn first aid technique that can keep the victims of sudden cardiac arrest (SCA) or other medical emergencies alive until medical professionals can take over.

CPR keeps blood pumping through the body, which helps maintain vital organ function. CPR has two primary goals: to keep oxygen flowing in and out of the lungs and to keep oxygenated blood flowing throughout the entire body.

Heatstroke and Sudden Cardiac Arrest

Heatstroke is no joke. Despite the fact that all heat-related deaths and illnesses are preventable, the Centers for Disease Control (CDC) estimates that about 658 people succumb to extreme heat each year. 

Sudden death — or sudden cardiac arrest (SCA) — can be brought on by a number of different causes including congenital heart defects, cardiac arrhythmia, commotio cordis, hypovolemic shock, and even electrolyte imbalances brought on by hyperthermia (heat stroke). 

Since we’re knee-deep in summer, we thought it was a good time to talk about heatstroke, its connection to SCA, and how to avoid it.

What Causes Heatstroke?

Heat-related illnesses are caused by exposure to too much sunlight and heat. When your body can’t cool itself adequately, you may start to feel over-hot, headachy, clammy, heavy, tired, dizzy, and nauseated. Your heart rate may increase as well. If this happens, it’s time to stop whatever it is you’re doing and find some water, shade, or air conditioning! 

Exposure to excessive heat can directly or indirectly cause some illnesses, and can certainly exacerbate preexisting conditions, such as heart and respiratory disease.

How Can You Prevent Heatstroke and Heat-Related Illnesses?

The CDC notes that “People at greatest risk for heat-related illness include infants and children up to 4 years old; people 65 years of age and older; people who are overweight or have existing medical conditions, such as diabetes and heart disease; people who are socially isolated; and the poor.” 

However, even young and seemingly healthy individuals can suffer from heat exhaustion or heat stroke if they’re engaging in strenuous physical activities during hot weather. Drinking alcohol, taking certain medications, or excessive exposure can put people at an even greater risk. 

Basically, anything that causes dehydration and inhibits perspiration or otherwise impairs your body’s ability to regulate its internal temperature can put you at risk of heatstroke. 

Here’s what you can do to stay cool:

  • Stay loose: Wear comfortable, lightweight, and light-colored clothing.
  • Put a lid on it: Protect your brain! Wear a hat or invest in a reflective umbrella.
  • Avoidance is okay: When the temperatures start to soar, stay out of the sunshine.
  • Exercise early: If you need to get a move on — and everyone should aim for 150 minutes of moderate activity each week — do it before 9:00 am or after 4:00 pm.
  • Drink up: If you are exercising in the heat, drink plenty of electrolyte-enriched water and take frequent breaks.
  • Get acclimated: If you work outside or you’re on a beach vacation, let your body acclimate to the heat before doing anything strenuous.
  • Circulation is your friend: If you don’t have air conditioning, be sure to use fans to keep air flowing in your home.
  • Slather on the sunscreen: Sunburn limits your body’s ability to keep itself cool. So even if it looks uncool, keep applying sunscreen.
  • Be a good neighbor: Check-in on folks who might be at a higher risk for heat-related illnesses such as elderly, disabled, or house-bound individuals.

Why are Electrolytes so Important?

Calcium, sodium, and potassium are the most important electrolytes in your body. “Calcium and potassium have to be in balance—sitting on either side of cell membranes, ready to switch places—in order to cause muscles to contract or nerves to transmit impulses. Once calcium and potassium swap places and cause things to happen, sodium puts them back in their place for the next time. If there aren’t enough of one or two or all of these electrolytes, then the heart muscle cells can’t move, which means the heart won’t pump,” (VeryWell Health).

And here’s what the American Heart Association has to say about electrolytes: “Electrolyte abnormalities are commonly associated with cardiovascular emergencies. These abnormalities may cause or contribute to cardiac arrest and may hinder resuscitative efforts.” 

Cardiac arrest brought on by heatstroke is 100% avoidable! Listen to your body, and before you head out into the sun, whip up a batch of homemade lemon-ginger electrolyte drink!

5 Things You Need to Do After a Heart Attack or Cardiac Arrest

Tips for Maintaining Whole-Body Wellness After Heart Attack or Sudden Cardiac Arrest

Regular readers of this blog know that heart attacks and cardiac arrest are not the same; however, some may be surprised to learn that a heart attack may lead to sudden cardiac arrest (SCA.) In what seems like a cruel twist of fate, it’s not at all uncommon for SCA to follow a heart attack. The greatest risk of a post-heart attack SCA is during the first 30 days after a heart attack (Duke Clinical Research Institute). Take heart: in this post, we’ll share a few tips and resources so that you can get back to living your best life and reduce the risk of post heart attack cardiac arrest.

Find a Support Network

If you’re feeling worried and anxious after your cardiac event, take comfort in knowing that you’re not alone. Many heart attack and sudden cardiac arrest survivors experience a host of emotions ranging from joyful gratitude to fear and trepidation. Life after a heart attack or SCA can be overwhelming, and for some may even feel uncertain.

It’s very common for heart attack and SCA survivors to experience anger, depression, denial, and anxiety. These feelings typically last for two to six months,and it’s important to recognize them and deal with them by seeking help. Your doctor should be able to recommend a mental health specialist who specializes in cardiac recovery. Let your loved ones know how you’re feeling, too. They can’t fully support you if they don’t know how you’re feeling.

For the first few weeks, it may be comforting to have someone nearby to help and support you. If you don’t have friends or loved ones who can stay with you, ask your care team to recommend resources near you. In the meantime, here are a few online resources to get you started:

Set Goals for Healthy Living

To minimize the risk of SCA or of having another heart attack — and to maximize your chances for a full recovery — it’s critically important to begin a regular fitness and activity routine as soon as possible. Be sure to consult with your physician before starting an exercise regime!

A few months ago we wrote a blog entitled 5 Strategies to Prevent Heart Disease, and while the strategies covered in the post are great for preventing a heart attack, they apply equally well to life after a cardiac event:

  • Eat a diet low in animal proteins, high in fiber, and rich with fruits vegetables.
  • If you’re overweight or obese, make a commitment to lose weight.
  • If you smoke, stop.
  • Develop a physician-approved exercise program.
  • Get plenty of rest.

“A healthy diet is one of the best weapons you have to fight cardiovascular disease. The food you eat (and the amount) can affect other controllable risk factors: cholesterol, blood pressure, diabetes and overweight. Choose nutrient-rich foods — which have vitamins, minerals, fiber and other nutrients but are lower in calories — over nutrient-poor foods. Choose a diet that emphasizes intake of vegetables, fruits, and whole grains; includes low-fat dairy products, poultry, fish, legumes, nontropical vegetable oils, and nuts; and limits intake of sweets, sugar-sweetened beverages, and red meats” (American Heart Association).

Find a Cardiac Rehabilitation Program

The Cleveland Clinic writes, “Patients who join cardiac rehabilitation programs have a faster and safer recovery and better outcomes after a heart attack. It is important to follow your cardiac rehabilitation team’s instructions for activity. Everyone recovers at a different pace. This may be related to your activity level before your heart attack or the amount of damage to your heart muscle. It may take many months to develop the optimal exercise program.”

By joining an outpatient cardiac rehabilitation program, not only are you committing to your recovery and living a full life after your cardiac event, but you’ll be doing so with a community of survivors. Many rehab programs are covered by insurance.

Take it Slow

Remember, recovery’s not a race! Your heart, mind, and body will need time to heal. Start by walking and slowly and gradually increase your pace. You should have slightly increased breathing, but you should be able to carry on a conversation. If you’re short of breath, slow down! If you’re walking outside, walk with a partner and stick close to home.

Once you’ve build your resilience back up by walking, choose an activity that you enjoy such as biking, swimming, or water aerobics and work it into your daily routine. Of course, if you are experiencing excessive shortness of breath, chest pains, heart palpitations, dizziness, or chronic fatigue, stop exercising and call your doctor!
