The 4 Best Portable Defibrillators and Which to Buy

Automated External Portable Defibrillator or AED for sale

If you look around you'll see them everywhere. They usually hang on the walls in airports, lobbies, schools, and other public places, but automated external defibrillators (AEDs) are becoming more and more prevalent in people's homes, cars, and offices.

Thanks to some companies pushing the envelope to make defibrillators safer and easier to use, they are now available over the counter without a prescription.


Buying a Portable Defibrillator

Sudden cardiac arrest (SCA) kills more people than traffic accidents, handguns, house fires, prostate cancer, breast cancer, and AIDS combined, about 350,000 per year.

It can happen to seemingly healthy people, but those with coronary heart disease and the elderly are at high risk. A family history of arrhythmias or heart related problems can also indicate higher risk.

While AEDs have been conclusively shown to save lives, keeping one in your house will far from guarantee a positive outcome after an SCA.

Although SCAs can happen anytime, anywhere, 75% of them occur at home[2]. Therefore portable defibrillators for those at high risk should save lives, but it’s not quite that simple.

AED Considerations

Cardiac Science aed at an airport in South AmericaPortable defibrillators are very efficient in high traffic areas such as airports.
  1. AEDs cannot be used by the person in cardiac arrest, so there must be another person nearby to see it happen. SCAs aren’t a common occurrence and may not happen to everyone who is at high risk, so it’s usually impractical to keep tabs on a high risk family member 24/7, especially considering at least 6-8 hours of each day are spent sleeping. In fact less than half of SCAs at home are witnessed[2].
  2. When an AED isn’t kept in the house and the first shock comes from arriving paramedics, the victim’s chance of survival is only 2%. One study found the survival rate of SCAs at home increased from 2% to 12% when an AED was kept in the house, but those numbers might not be completely accurate because the study didn’t have enough participants to accurately represent the whole population.
  3. SCAs usually happen so fast the person having one cannot notify anyone.
  4. Instead of having AEDs in homes or targeting specific, high-risk patients, AEDs are most efficiently used in high traffic areas. For this reason many public places like airports, schools, and office buildings have defibrillators available in wall-mounted cases.

The bottom line is that portable defibrillators are expensive and only raise your chance of success from terrible to bad, but they do raise your chance of success. Taking a CPR course as a family along with having a portable defibrillator will also improve outcomes. Check out our article on CPR for more information.

AED Price

The Philips Heartstart Home defibrillator is the cheapest portable defibrillator I have found.

Despite having no functional differences, the Home defibrillator is sometimes offered at a significantly cheaper price compared to the OnSite defibrillator.

The products function exactly the same way; the only difference is their warranties: the warranty of the Philips Home version will only cover malfunctions that happen in the home, while the warranty of the Philips OnSite covers the portable defibrillator anywhere.

Portable Defibrillator Accessories

When purchasing an AED you may also consider purchasing several other items that will be useful for a CPR scenario.

CPR training-05

CPR Pocket Mask

The mask has a 1-way valve to provide assisted breathing during CPR. It covers the patient's mouth and nose and provides a barrier to prevent the transfer of body fluids between you and the patient.

A smaller alternative to the pocket mask is a disposable plastic barrier with a 1-way valve. If you already have a portable defibrillator, the pocket mask will fit easily inside the AED case, so size shouldn't be an issue.

The disposable barrier comes in a little pouch that is small enough to fit on a keychain. When giving breaths with the disposable barrier you will need to hold the nose shut as the barrier only covers the mouth.

When providing CPR, having a barrier is a very good idea because patients often vomit due to the pre-existing heart condition that caused the heart attack or during chest compressions from pressure on the stomach.

Pediatric AED Pads

Pedriatic pads for an automated external defibrillator

The AED comes with pads that are sized for adults. Pediatric pads are designed for children under 8 years old or under 55 lbs (25 kg). If you are in a situation where a child has a heart attack and you only have adult pads, an AED CAN still be used.

For small children place the right-shoulder pad on the chest and the left-ribs pad on the back. The AED will decide whether or not to shock the patient.

When paramedics arrive on the scene they will remove the pads and replace them with their own. When using pediatric pads each one will have pictures that show where it goes.

AED Wall Cabinet

It is used to store an AED in a public space or a high traffic area. A wall cabinet keeps the automated external defibrillator visible and readily available at all times. They require an AED location plan for maximum efficiency. For more information, read our article: AED Wall Cabinet Recommendations and Regulations

Nitrile Gloves

Often times the patient will vomit during CPR. If something is stuck inside their mouth the first responder needs to swipe it out. The point is, gloves will protect you and the patient from exchanging body fluids.

Portable Defibrillator Tips

Resuscitace za použití AED (02)
  1. You CAN'T use this on yourself.
  2. A portable defibrillator CAN be used on a pregnant woman. In order to save the baby you have to save the mother.
  3. If a child goes into sudden cardiac arrest and you only have adult defibrillator pads, you SHOULD connect the pads regardless. The AED will decide whether to shock.
  4. When instructing bystanders to call 911 and/or get an AED it’s most effective to point at a single individual. Giving general commands to a crowd makes it confusing who is supposed to go.
  5. The use of an AED is covered under Good Samaritan laws. This means that if you use a portable defibrillator to help someone in good faith, you cannot be held responsible should something go wrong[3].
  6. New research shows that raising the legs during CPR causes increased blood flow to important organs like the brain, increasing the chance of survival[4].


  • Portable defibrillators are extremely easy to use
  • The Philips Heartstart OnSite/Home Defibrillator and the Zoll AED Plus are the only non-prescription AEDs
  • The only difference between OnSite and Home defibrillators is the warranty
  • Coronary heart disease, family history, and old age increase risk of sudden cardiac arrest
  • Use CPR in conjunction with AED
  • If sudden cardiac arrest is witnessed, call 911, get AED, start CPR in that order
