What's to like about the Philips HeartStart OnSite Defibrillator AED

The CPR assist on the Onsite AED is top-of-the-line. The unit will give on-demand CPR instructions throughout the defibrillation process which makes it a more effective, easy-to-use tool during a rescusitation procedure. This system even has a metronome which will help you keep time during compression periods of CPR.

Another positive of this model is the battery setup. The lithium-ion batteries should be replaced every four years and are very easy to change since the battery has a simple back compartment. This model can even be used with aviation-grade batteries, which is a unique feature that is not often found with AEDs.

What's not to like about the Philips HeartStart OnSite Defibrillator AED

The pads and batteries both need to be replaced fairly frequently at 2 years and 4 years, respectively. While this may not seem that often, other AEDs don’t need to be replaced until 5 years or more, so it can be a large add-on cost.

This model is not so advanced that it has any ECG information on its display screen. It does show some graphical information, but EMS and medical users may want an AED that has a more advanced screen.

Once again, it is important to remind everyone that this is not a live AED. It will not deliver shocks; it is only for training purposes.

Another drawback of this model is the pad cost. While the training pads are reusable, they will wear out before the device so you will need to replace them every few months if doing a lot of training sessions.

BUYER'S GUIDE

Buying an AED can be a difficult process. You’re buying the product with the knowledge that it might someday be used to save someone’s life, so you have put careful consideration into its selection.

But what characteristics matter most? This guide will help you determine that.

Price

While you can’t put a price on saving a life, the simple fact is that every school, business, home, or public establishment is going to have a budget on how much they can spend on an AED.

Some very expensive AED can cost well over $3,000, but most range from $1,000 to $2,000. There are a lot of small variations between these models, but you should plan to budget somewhere in this range when adding an AED to your safety protocol equipment.

Brand

There are a number of reliable companies that sell AEDs. Each brand has its own reputation and price point, but there isn’t a huge difference between them.

All of the following brands are known to have reliable products that can help you save a life. Select a product from one of these brands for the best results:

  • Defibtech
  • Philips Heartstart
  • Heartsine
  • ZOLL
  • Physio Control LIFEPAK
  • Cardiac Science Powerheart

If you can’t choose between these brands, it is recommended that you choose a brand that can be serviced locally. It’s important that you do the AED maintenance periodically to be sure it is working, so you will want to be able to do this somewhere nearby.

Ease Of Use

Like all technology, some is simply more intuitive to use. When it life-threatening, seconds are ticking by, you want to make sure the AED you own is easy to use. If it’s too complicated, it will be easy to forget what to do in a moment of stress.

There are important differences to pay attention to when making your choice. Some AEDs have audio and visual aids; while older or less technologically advanced models may only have written instructions. Some are set up to assist with CPR.

CPR assist is becoming more and more popular with AED devices since CPR is required in 100% of AED-use cases while shocks are only delivered about 70% of the time. With CPR-assist, the AED will instruct you on how to adjust your CPR depth and rate of compression to ensure the most effective help is being delivered.

In a time of emergency, this can be incredibly beneficial as it gives you a clear guide on how to help the patient as much as possible, so consider looking for a CPR assist-enabled device if possible.

You also want to make sure that the upgrade process with your chosen AED is easy for you to do. Some AED models may have to be taken to a service center to be upgraded; others can be upgraded at home by connecting them to the internet. Check this when choosing your device.

Training Compatibility

For any establishment that plans to do CPR/AED training with the purchased AED, you will want to make sure you are buying an AED that is compatible with the course material. Though AEDs all function in very similar ways, different courses expect you to use different AEDs, so it is important to check this information before making any purchases.

Remember the following if training compatibility is important for your AED unit:

  • Not all AEDs can be used in training mode; some require that you buy a separate training version that should be used during this process
  • For AEDs that can be used for training, you must replace both the live batteries and the pads to do the training. The specifics of this may alter between various devices
  • Having a separate training AED may be beneficial so that you do not damage or deplete your main AEDs battery during training hours
  • Training AEDs cost more upfront but may save you on maintenance costs in the long run since you won’t be using your main unit too frequently

Whether you decide to have a separate training unit or not, the key point is to remember to check that the AED you choose is compatible with your training courses.

Consumables (Batteries and Pads)

An AED does need to be serviced from time to time to ensure that it keeps functioning properly. The main things that need to be serviced are the batteries and the pads.

Batteries on an AED should be replaced every 1 to 3 years depending on the particular model that you purchase. Pads are typically replaced every 2 to 5 years. Again, this may vary.

The particulars of when pads and batteries need to be replaced will be detailed in your AED’s instructions, but you want to look up this information before making a purchase.

Why? Because battery and pad replacements are going to add to the total cost of your AED over time. The price of these replacements varies largely between devices, so knowing the cost in advance can help you to save money or at least be prepared for the future cost.

Warranty

Every AED will come with some type of warranty. As a base standard, this is usually 5-years. However, every company has some differences.

The best AED will come with at least a 5-year warranty and offer the option to allow you to buy an extended warranty for even longer. The longer the warranty, but better off you are. The warranty value may differ between providers, but you want to ensure you have at least some warranty on your AED to protect you from the cost of errors or damages.

AED FAQs

What Is An AED?

AED is short for an automated external defibrillator. An AED is a light, portable device. When used, it sends an electric shock through the chest and into the heart. The goal of using an AED is to push a heart back into a normal rhythm when an arrhythmia (irregular heartbeat) develops after a sudden cardiac arrest.

Tutorial: How To Use An AED?

An AED can make a huge difference in someone’s chance of survival, but how do you actually use one?

Every AED is different, but they have the same basic characteristics which make it possible for anyone who knows how to use one AED know how to use them all. This is key, so you should learn the basic steps and remember them carefully.

This video gives a great overview of how most AEDs can be used:

How Does A Defibrillator Work?

Now that you know the basics of how to use an AED, you may want to know more about why and how a defibrillator works.

When the heart’s rhythm begins to beat irregularly due to cardiac arrest, this can be life-threatening if a regular rhythm is not restored quickly. A defibrillator delivers an electrical shock in an attempt to restore the heart’s natural rhythm.

In the case of an AED, an automatic external defibrillator, the device analyzes the heart’s rhythm to determine whether or not an irregular rhythm is happening. If it does, the AED will calculate when and how much to shock the patient in an attempt to help them.

Electrodes are placed on the patient’s chest, and the AED analysis occurs. Then, the AED sends a shock to the heart through the chest. Ideally, this electric shock would stop the irregular rhythm and “reset” the rhythm back to normal.

Using an AED in combination with CPR can increase the rate of survival in cardiac arrest cases by more than 70%, so having one available is key in this kind of situation.

Timing: When To Use An AED?

In an emergency situation, it can be very stressful to determine when to use the AED. Thankfully, there is an advised method that should be followed in situations where cardiac arrest seems to be affecting the patient:

  1. Call 911. This should always be done first so that trained medical professionals get there as fast as possible.
  2. Begin CPR while someone retrieves and starts up the AED.
  3. Follow the AED instructions to set up, and then use the AED to shock the patient.
  4. Continue giving CPR and following the AED’s instructions about when to deliver another shock until emergency services arrive.

Once EMS arrive, they will take over. Starting CPR immediately and using the AED as quickly as possible is key to saving a life. The first five minutes of cardiac arrest are the essential care period, so be sure to act quickly and confidently even if you are afraid.

How Many Joules Does An AED Deliver?

Older AED models deliver between 360 and 400 joules. In some cases, this caused burns at the pad sites and even some cardiac injury.

Since then, newer models that deliver lower-energy, sequential shocks at between 100 and 200 joules. This reduces the risk of injuries occurring while also reducing the amount of recovery time needed after the use of a defibrillator.

FINAL VERDICT

Without quest, the best AED on the market is the Philips HeartStart OnSite Defibrillator AED. This widely used AED is reliable, easy-to-use, and provides both AED and CPR assist during emergencies.

If you need a training unit, the complementary OnSite Professional Trainer is a great choice as it will prepare you to use your live AED effectively.
