Why YSK: TV has lied to you. If a cardiac arrest happens and you have an AED defibrillator at hand you might still need to do chest compressions.
- When you open up the AED there will be instructions on how to apply the electrodes as well as any other procedure needed to get started.
- The machine will first analyze the heart’s rhythm to find out if a shock can restore the heart.
- If the machine doesn’t find anything it will instruct you to perform CPR. After a while it will then instruct you to stand by as it does another analysis.
- It will once again either deliver a shock or instruct you to go back to CPR. Do this routine indefinitely until medical services has arrived. You will be tired. Switch out with another person if there are other people who can help.
- Some AED’s are automatic and will warn you to stand back and deliver a shock. Others will need you to press a button to deliver the shock yourself. Make sure not to touch the person as the machine delivers the shock.

Not a doctor but I think AEDs can only fix an arhythmic pulse as is the case when ventricular fibrillation occurs.
Ah, ha, ha, ha, stayin’ alive, stayin’ alive
For those curious about what a defibrillator does do: It stops hearts.
Which might seem insanely counterintuitive, but it’s great for when the heart gets stuck in a rhythm that prevents it from being able to pump properly, since stopping it lets it restart itself in a more normal rhythm.
Before we invented the defibrillator, doctors basically had to punch the patient in the chest to hopefully hit the heart at the right point to stop it. It does also mean that if you really know what you’re doing, and got lucky with the timing/amount of force, you could technically pull off one of Kill Bill’s death punches, although it would be a little less dramatic than them walking five steps before their heart explodes.
But unlike video games, unless you fry the heart itself, a defibrillator won’t instantly kill someone. It will stop their heart, sure, but their heart will restart itself, unless something is wrong (stopped for too long, physical damage, irreversible chemical imbalance, etc)
The other thing they don’t say during cpr class is that the resuscitation rate for an out of hospital cardiac arrest is 9.1%.
One of the biggest factors in survivability is the time to initiate CPR in the time the compressions are interrupted. My EMS department has moved away from a AHA to high performance CPR. 
What is an AHA and what is high performance CPR?
One thing to add, that haven’t been thought to me in the CPR course.
It’s fucking exhausting and you will get tired very soon. The training dummy doesn’t require nowhere near as much force as a real person. To give you an example, it’s quite common to crack or break a rib of the CPR recipient even if CPR is done right. That’s how much force you have to use. Without the required force, your pushes won’t reach the heart.
Make sure there is someone else who knows how to do CPR or at least is looking how you’re doing it and can repeat that or follow your commands once you switch.
I’ve only had to give someone CPR once and I haven’t been as tired in my whole life. No way the “I’ve been giving him CPR for 30 minutes…” You see on a TV screen is real. I felt like I’ll need CPR myself after 3 minutes.
Dixit my CPR trainer:" He’s already dead. You can’t kill him more."
“challenge accepted”
It’s concerning how there is no AED/CPR training in school considering everyone is likely to run into a situation where a family member will need resuscitation while waiting for an ambulance. Not knowing when and how to do cpr, how to use a defibrillator (portable ones give audio instructions) etc is so dangerous because by the time an ambulance gets there it may be too late. Also I wish AED were more readily available and easily located. May even be a good idea to pitch in with neighbors and make a locked box that’s easily accessible.
Here, in the Netherlands, we have a network of civilian first responders, with people that will be alarmed by the 112 (for you Americans: that’s the European version of 911) call center when a CPR request is near them. Also, we have a practical full cover over the country of AEDs. We have one against our front wall, accessible for everyone. In 1.5 years of time, I got two times a call that I was able to respond to, but our emergency services were already present when I arrived (by bike) on the location.
I’ve heard this before and looked it up, but I found this article from the NIH that contradicts what you’re saying.
Defibrillators are devices that send an electric pulse or shock to the heart to restore a normal heartbeat. They are used to prevent or correct an arrhythmia, an uneven heartbeat that is too slow or too fast. If the heart suddenly stops, defibrillators can also help it beat again.
The way a defibrillator works with a stopped heart is by analysing, and it that way it does “help it beat again”. But it won’t shock a stopped heart. The name says it all; it de-fibrillates. The heart has to be fibrillating for it to be de-fibrillated; the shock can only correct an archaic rythmn, not the absence of rythmn.
If there’s no electric activity, the person needs meds like epinephrine, not a shock.
The thing with TV shows, is that they often show a flat line on an ECG monitor and then shock the patient, which is basically useless except at burning the patient’s skin and stopping effective compressions during CPR. The kind of ECG we should see during a shock is atrial fribrillation (a-fib) and ventricular fibrillation (v-fib). Those should have a very wavy ECG line.
Source: am nurse (edit: a better nurse corrected me on some differences between shocking for a defibrillation and for a cardioversion, go read their comment)
There are certain devices that do do that, but it’s not a defibrillator. A defibrillator will stop/prevent an arrhythmia by stopping the heart, and letting it restart on its own (hoping that it goes to a normal rhythm), and delivering further shocks if it gets back into one.
The device you’re looking for to help a heart beat again would be a pacer, or a pacemaker, which will shock the heart to force it to pump, and restore rhythm that way. They’re commonly used for conditions like heart failure, if the heartbeat generation systems/internal pacemaker can’t generate a heartbeat quickly enough to sustain life.
It’s like we’re redoing the basics of reddit. :)
We do not use 10 percent of our brains.
(This is jest, not complaining)
True true. I think I see it like this good old xkcd.
