Philips HeartStart AED  Product Detail
Model: OnSite

The HeartStart OnSite Defibrillator is designed for the ordinary person in the extraordinary moment. Our innovative technology, based on extensive research and user feedback, has produced a defibrillator so easy to use that, with minimal training, you can potentially save the life of a co-worker, friend, or anyone else stricken with sudden cardiac arrest. The Onsite AED Treats the most common cause of Sudden Cardiac Arrest by delivering a shock to the heart.

Weighing just 3.3 lbs., this small and lightweight defibrillator can be easily carried to the patient’s side. Using clear, natural voice instructions, the OnSite Defibrillator guides you, the first caregiver on the scene, through each step of defibrillation and CPR. Integrated SMART Pads placed on the patient’s bare skin transmit information to the defibrillator, which senses and adapts to your actions every step of the way.

HeartStart OnSite includes proven Philips technologies for heart rhythm assessment (SMART Analysis) and defibrillation energy delivery (SMART Biphasic). And like all HeartStart defibrillators, it can be used to treat infants, children and adults.

Easy to Use
  • Uses clear, natural voice instructions that talk you through each step

  • Senses and adapts to your actions

  • Coaches you through CPR

  • Based on industry-leading technology

  • Uses a highly accurate algorithm to determine whether the patient’s heart requires a shock

  • Designed to only deliver a shock if one is needed

  • Performs comprehensive daily self tests

  • Ready to use when you need it

  • Check its status at a glance

Lead the well-equipped life.

With more than 175,000 devices deployed, Philips is the worldwide market leader in portable defibrillators on airplanes, and in airports, workplaces, communities, and homes. The Philips HeartStart Home Defibrillator is the first and only home defibrillator available without a prescription for use by virtually anyone to help save a life when minutes count. This award-winning defibrillator has consistently been recognized for its ease of use.

Ready When Needed

HeartStart Onsite is powered by a simple, safe, long-life (four-year) battery, the same technology used in cameras. Just click the battery in place, and the defibrillator is standing by, ready for use.

Between uses, the defibrillator performs daily, weekly, and monthly self-tests of its electrical components, subsystems, and battery to help ensure continued reliability and readiness. A pads integrity test, which checks daily that the cartridge is properly installed and that the defibrillator pads are in working order, provides an additional level of assurance.

As long as the green “Ready” light on the defibrillator is blinking, you can be certain the HeartStart OnSite is ready for use. If any part of the defibrillator needs attention, the “Ready” light turns off and the defibrillator “chirps” to alert you. Pressing the flashing blue “Information” button provides verbal guidance to help you identify and correct the situation.


Using the HeartStart OnSite Defibrillator is simple. Pulling the green handle powers-up the defibrillator and activates voice instructions. These instructions are paced to your actions, to help guide you through the entire process, from placing pads on the patient to delivering a defibrillation shock.

HeartStart OnSite determines if a shock is needed, based on its automated assessment of the victim’s heart rhythm:
  • If a shock is needed, the defibrillator directs you to press the flashing orange “Shock” button. Then, HeartStart OnSite delivers a dose of low-energy biphasic therapy, a highly effective defibrillation waveform that is also gentle to the heart.

  • If a shock is not needed, the OnSite Defibrillator instructs you to assess the patient and to perform CPR when necessary. While performing CPR, the defibrillator’s voice instructions can be activated to coach you on the frequency and depth of compressions.

HeartStart OnSite also reminds you to call emergency medical services (EMS). And, should EMS need a summary of care, it can be retrieved from the defibrillator’s internal memory. An EMS provider simply presses the “i-button” and HeartStart Onsite verbally recounts events from its last clinical use.

The OnSite is just one part of a well-designed emergency response plan. Any emergency response plan should be under the oversight of a physician and include CPR training. Ask your HeartStartCentral representative about Medical Direction.
