What to Do When your AED Decides No Shock is Advised

So, you find yourself in a situation where someone is in dire need and your trusty Automated External Defibrillator (AED) does its thing and…wait for it…refuses to give a shock! What is going on? Is your AED just having a bad day? Fear not, my friend, because I’ve got some insights and tips to help you navigate this unexpected twist.

Understanding the “No Shock Advised” Situation

When your AED calmly declares “No Shock Advised,” it’s not being heartless (pun intended). In fact, it’s actually trying to be quite clever. You see, an AED is designed to analyze a person’s heart rhythm and determine whether it’s necessary to administer an electric shock. And sometimes, the unpredictable human heart throws a curveball, leaving the AED with no choice but to hold back on the shock therapy.

Check for Proper Electrode Placement

Now, before you throw your hands up in frustration, take a deep breath and double-check those electrode pads. Are they correctly placed on the person’s chest? Sometimes, improper placement can confuse our electronic lifesaver, causing it to think a shock is unnecessary. Give those pads a quick once-over, making sure they’re securely attached and correctly positioned. You don’t want a heart to miss out on some vital defibrillation simply because of poor pad placement, right?

Assess the Person’s Condition

While the AED works its magic, it’s great to lend a helping hand by assessing the person’s condition. Are they conscious? Are they breathing normally? Checking these important factors will help you determine whether any immediate action, like CPR, is needed. Remember, even if the AED doesn’t recommend a shock, it doesn’t mean you should just stand by and sip a cup of tea. Assessing the whole picture is crucial in providing the best care possible.

Double-Check the AED’s Battery and Connections

Ah, batteries. They can be the cause of many frustrations in life, from a TV remote dying at the crucial moment to an AED refusing to cooperate. Ensure your AED is properly powered by checking the battery level. If it’s low, well, you know what to do. And while you’re at it, make sure all the cables and connections are securely fastened. A loose connection might contribute to the AED’s reluctance to deliver a shock.

Call Emergency Medical Services ASAP

Now, here comes the crucial step: contacting Emergency Medical Services (EMS). Even if the AED says no shock is advised, it’s always wise to seek professional help. Pick up that phone and share the details of the situation with the trained emergency dispatcher. They will guide you through the necessary steps and provide invaluable advice until medical professionals arrive on the scene.

Continue Basic Life Support Measures

Persistent as ever, you’ve done your due diligence by checking the electrode pads, assessing the person’s condition, ensuring the AED is properly connected, and contacting EMS. But wait, there’s more! Don’t hang up your superhero cape just yet. Continue with basic life support measures, such as CPR and maintaining an open airway, until further help arrives. Remember, your efforts can make a real difference in someone’s life.

Reflect and Learn for the Future

Once the dust settles and the adrenaline rush subsides, take a moment to reflect on the experience. Review the events leading up to the AED’s “no shock advised” declaration. Were there any signs or symptoms that you might have missed? This post-event reflection will not only help you grow as a responder but also prepare you for future encounters with your trusty AED.

So, the next time your AED refuses to administer a shock, don’t panic. Check the electrode placement, assess the person’s condition, ensure proper battery and connections, call EMS, and continue providing basic life support. Remember, even without a shock, your actions and calm presence can be a lifeline in themselves. Stay prepared, stay positive, and keep being a hero in your own unique way!

FAQ: What to Do When AED Says No Shock Advised?

So, you’re faced with a situation where the automated external defibrillator (AED) insists on being a party pooper and declares “no shock advised.” Don’t worry, we’ve got you covered! We’ve compiled a list of frequently asked questions to help you navigate this situation with ease. Let’s dive in!

How Fast Should You Do Chest Compressions When Resuscitating

When it comes to chest compressions during resuscitation, think of your hands as your DJs and the beat they create as the rhythm of life. You want to keep that beat steady and strong to maximize the chances of reviving the person in need.

So, here’s the deal: aim to deliver those compressions at a rate of 100 to 120 beats per minute. You might be familiar with the tune “Stayin’ Alive” by the Bee Gees. Well, it just so happens that the rhythm of that catchy disco classic matches the ideal compression rate perfectly. Isn’t that music to your ears?

Should You Leave AED Pads on if No Shock Is Advised

Picture this: The AED says a firm “no” to delivering a shock, but it doesn’t mean the party is over. Keep those AED pads firmly in place because they’re not just for decoration. They are the life-saving adhesive that connects you and the person in distress to the AED’s watchful eye.

Leaving the pads on ensures the AED can continue monitoring the person’s heart rhythm and provide you with any further instructions if needed. Think of it as the AED’s way of saying, “I’m still here for you, just in case the beat starts to drop again.”

Do You Shock a Flatline

Ah, the dreaded flatline. It’s like attending a karaoke night with no hits on the playlist. But here’s the thing: When you’re dealing with a flatline, shocking is as effective as using an umbrella on a sunny day—it won’t make any difference.

When the AED displays a flatline, it means that the heart’s electrical activity is completely absent. In this situation, the focus shifts from shocking to high-quality CPR. So, get your hands in position, give those chest compressions, and let the rhythm of life build up gradually.

Is It OK to Only Do Compressions If You Don’t Want to Give Breaths

Breaths—it’s like the dynamic duo of CPR, right? But let’s say you’re not comfortable or you simply don’t want to give breaths. No need to panic. You can still make a difference!

The American Heart Association (AHA) affirms that hands-only CPR is better than standing idly by. So, go ahead and embrace the beat; push hard and fast on the person’s chest to the tune of that good old 100 to 120 compressions per minute. Remember, being a hero doesn’t require singing like Celine Dion; it’s all about being the rhythm master.


Congratulations! You’ve now conquered the FAQs surrounding the moment when the AED decides “no shock advised.” Armed with this knowledge, you’re more than ready to handle unexpected dance breaks in the journey of resuscitation. Keep your head up, your knowledge sharp, and be the life-saving enthusiast that you are!
