HeartStart HS1

  • AED defibrillator designed for ease of use and prompt response
  • Step-by-step voice commands and CPR guidance provide real-time guidance
  • Easily converts to an AED trainer when you attach training pads (sold separately)
  • Slim AED Carry Case accommodates defibrillator and paramedic scissors
  • AED ships with: HeartStart Home AED Defibrillator, pre-installed battery, pre-installed adult SMART pads cartridge, quick setup guide, maintenance booklet, quick reference guide, owner’s manual, Slim AED Carry Case, training DVD, and one adult AED Training Pads Cartridge

Philips has quite a few AED devices on the market. The best way to check which one you’re looking at is to find the model number. This is the M5068A-C02 model (for home use), which has FDA approval along with the OnSite model here.

It’s designed to be used at home for sudden cardiac arrest. This model comes with a carry case, training DVD, maintenance booklet, quick set up guide, and owner’s manual. Be prepared to pay a hefty sum for this AED set.

The AED device comes with adult SMART Pads that are designed for use on adults over 25kg (55lbs). There are other SMART pads you can buy from Philips to use with this device. Infant pads are the right size and shape for children under 8 years and will lower the energy level of the shock so it’s more appropriate.

We like that you can also buy training pads for this defibrillator, so you can use it to train yourselves before you need to use it for real.

This was also the first AED defibrillator to be sold in the USA without needing a prescription to use it. Philips pride themselves on offering a device that is incredibly easy to use.

The unit has an 8-year warranty but bear in mind that the battery only has 4 years on the warranty and pads have just 2 years.

    • The Slim Carry Case (M5076A) holds the OnSite Defibrillator and a pair of paramedic scissors
    • Guides you through every step – just pull the green handle to activate your onsite defibrillator, and life guidance voice instructions will calmly and clearly guide you through the entire process

    • What Is Included – Defibrillator, Battery, Adult SMART Pads Cartridge(1 set), Setup and Maintenance Guides, Owner’s Manual, Quick Reference guide, Date Sticker.Battery type:9 Volt DC

Just like the home model, this device is approved by the FDA (see product above for the link) and has many of the same features. But the OnSite AED defibrillator – model number M5066A-CO2 – is not designed for use at home. Instead, it’s designed for use in a business environment. For offices, gyms, shops, and other businesses, this device could save a life.

This Philips defibrillator works in exactly the same way as the model above. Once you’ve opened it up, you just need to pull the green tab to turn on the device and it will guide you with voice instructions.

The intuitive SMART analysis detects the heart rhythm when attached, to give you guidance on whether a shock is needed, and when to perform CPR. Furthermore, it will also give you feedback on the depth and frequency of CPR compressions, plus the breathing rate of the person.

Despite being designed for business use, it’s completely accessible for anyone. You don’t need training or a prescription to use this AED in your home. Some people prefer to have the OnSite model over the Home model, even for personal use.

If you are using this for a public space, make sure you check state regulations. You may need first aid training and CPR training besides the AED. Rules vary from state to state.

Just like the first Philips AED, you’ll need to buy separate SMART pads for using this machine on infants or for training practice.

Philips, the leader in portable defibrillation technology, designed the HeartStart OnSite Defibrillator for the ordinary person in the extraordinary moment. The first commercial defibrillator available without a prescription, the OnSite is designed to be the easiest to use and most reliable defibrillator available.

Philips Heartstart FRx defibrillator

Philips SMART Biphasic technology enables individual treatment, based on specific casualty needs, increasing their survival rates following a cardiac arrest. The IP55 rating of the FRx maximises protection against dust and water and it’s sturdy design can withstand weights of over 200 kilos.  On top of this, the FRx is showerproof and offers protection against accidental dropping.

SMART Analysis : Philips has developed a technology that assesses the patient’s heart rhythm and ensures the Philips FRx defibrillator only delivers a shock if it is required. So even if there is a panic during the rescue process and someone presses the button too hastily, it will not administer the shock unless it’s needed.

Paediatric Function : To switch the defibrillator to work on a child all you have to do is insert the optional Infant/Child Key. The device’s preconnected SMART Pads II are suitable for use on both adults and children alike. So no time is wasted switching pads. And there’s no extra expense buying different electrode sizes for different patient types.

Philips HeartStart OnSite AED Review

The Philips HeartStart OnSite AED is one of the most popular portable defibrillators on the market, in production for over a decade. But is it worth the investment when you compare it to other devices in its class? We hope that our Philips HeartStart Onsite AED review will provide clarity and make your buying choice a little easier.

HeartStart OnSite Overview

Originally introduced in 2004, The Philips HeartStart OnSite represents a technological leap forward from the earlier ForeRunner and FR2/FR2+ AEDs. With its intuitive features and user-friendly design, the OnSite remains one of the only AEDs approved by the FDA for over-the-counter sales (no prescription required).

How Much Does HeartStart OnSite Cost?

What We Love About the Philips HeartStart OnSite

  • The Price: At $1,275, this is the most affordable AED available in its class. It’s backed by an industry-leading 8-year warranty, so the total cost of ownership is especially impressive.
  • Usability: You’ll be hard-pressed to find an AED that’s easier to use. Just press the green “Power” button to get started, and the OnSite guides you through the entire CPR and defibrillation process.
  • Product Readiness: This device is ready to use right out of the box. The pads and battery come pre-installed, and the software is preconfigured to respond to an emergency without any setup required. Just pull the green tab to initiate the first self-test. The OnSite takes care of the rest.
  • Biphasic Waveform Technology: The OnSite is equipped with Philips’ patented SMART Biphasic waveform technology, which uses alternating currents to save lives with less electricity required.
  • Quick Shock: This device can deliver a shock in as little as 8 seconds following CPR. Subsequent shocks are typically delivered in under 20 seconds. This AED is one of the fastest in its class when it comes to shock delivery, which results in more positive outcomes for cardiac arrest patients.

Drawbacks of the Philips HeartStart OnSite

  • Infant/Child Pads Not Included: The OnSite doesn’t contain the Infant/Child Key that has become a staple of more recent Philips AEDs. If you’re purchasing the device for pediatric use, you’ll need to purchase a special set of pediatric SMART pads. A prescription is required for the pediatric pads.
  • No Automatic Shock Delivery: This is a very minor quibble, but it’s worth noting for those users who are timid about administering electrical shocks. While some newer AEDs have the option of automatic shock delivery, this one does not. The device will assess the heart in search of a shockable rhythm and then prompt you to press the “Shock” button if treatment is advisable.

Features of the Philips HeartStart OnSite


Score: 5/5

Simply put, you’ll never find a more user-friendly AED. The Philips HeartStart series was specifically developed to make defibrillation technologies accessible to the lay user, and the OnSite more than delivers on that mission.

As soon as you turn on the device, you’re prompted step-by-step by calm, clear voice instructions. The CPR metronome gives you the confidence to perform chest compressions at the optimal pace, and the SMART pads are clearly diagrammed for easy chest placement. The AED even reminds you to call emergency medical services, so you never have to worry about missing an important step if your mind is racing in an emergency.

The device even works as a trainer. You can install a special cartridge and practice emergency procedures safely in your spare time.


Score: 5/5

Philips invented the use of biphasic waveform technology in an AED—and they still do it better than anyone. Philips SMART Biphasic technology has been demonstrated in more than 40 peer-reviewed studies to treat patients with greater effectiveness and fewer side effects.

Not only is the OnSite equipped with Philips’s patented biphasic technology, but the device uses SMART Analysis to automatically assess a patient’s heart rhythm. The device then makes a rapid determination as to whether an electrical shock would be safe and feasible.

You are only advised to press the “Shock” button if the algorithm confirms that doing so would provide a safe and beneficial outcome for the patient. If you accidentally press the “Shock” button when electricity is not advised, the device will not proceed with the shock delivery. Not every AED has these kinds of safeguards in place.

The device runs daily, weekly, and monthly self-tests to ensure readiness at all times. Over 80 tests per month are performed.


Score: 4/5

Though it’s not the lightest or most rugged AED available, the Philips HeartStart OnSite is pretty tough. It can withstand drops of up to 1 meter, and it’s designed to operate in temperatures ranging from 32 – 122 °F. And because it weighs just 3.3 pounds, it’s easy to store and transport.


Score: 4/5

Philips wrote the book on child-friendly AEDs, and the OnSite is one of, if not THE best pediatric defibrillators around. With the SMART Pads Cartridge installed, anyone can safely perform CPR and defibrillation on pediatric patients. The voice and visual coaching are automatically modified to meet the needs of young patients, and the shock delivery is decreased from 150 Joules to a safer 50 Joules.

The only drawback is that you will need to invest in a set of child-friendly pads. If you want the ability to treat both adult and pediatric patients without switching pads, consider investing in the HeartStart FRx or FR3—both of which feature Philips’ enhanced Infant/Child Key for more streamlined treatment.

The Verdict: Should You Buy the Philips HeartStart OnSite?

We strongly recommend Philips defibrillator products. They are simply the most advanced and user-friendly on the market. The only question that remains is: Is the OnSite preferable to other HeartStart models?

Newer models like the FR3 and FRx do offer more advanced, streamlined features, but they also come with a much higher price tag (and, in the case of the FR3, a steeper learning curve).

If you’re looking for a cost-effective defibrillator that will last for years and never disappoint you in an emergency, the Philips HeartStart OnSite is an excellent buy that we wholeheartedly recommend.
