Each year sudden cardiac arrest (SCA) strikes approximately a quarter-million people in the U.S.  alone. The majority of these people have no warning, since they show no prior symptoms. And, sadly, fewer than 5% survive, often because emergency medical services cannot reach them in time.  When sudden cardiac arrest strikes, the electrical system of the heart short-circuits, most often causing an abnormal rhythm known as ventricular fibrillation.  Lacking proper blood flow, the person loses consciousness, stops breathing, and will die unless promptly treated. CPR (cardiopulmonary resuscitation) can help a person in cardiac arrest, but it alone cannot save lives. A “shock” from a defibrillator —defibrillation therapy — is needed to restore the heart’s normal pumping rhythm. A victim’s best chance of surviving SCA is to receive that shock within 5 minutes of collapse.

The Movement to Save More Lives
Over the last 20 years, there has been a widespread effort to move defibrillators into communities where they can be accessed and used by trained citizens, who might be present at the onset of SCA or first on the scene. To that end, Philips produces easy-to-use automated external defibrillators. Our HeartStart defibrillators enable almost anybody to treat SCA quickly and effectively, wherever it happens — at work, at play, in the air — providing the power to save a life.

The HeartStart OnSite Defibrillator
Philips, the leader in defibrillation technology,* designed the HeartStart OnSite Defibrillator 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.

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.

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.

Easy To Use

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.

HeartStart OnSite Defibrillator is designed to enable you to help save a life in extraordinary circumstances.
• Lightweight: Fully equipped at just 3.3 pounds.
• Intuitive: Clean design and clear voice instructions instill the confidence that’s needed when administering therapy to a person in cardiac arrest.
• Ever-Ready: Powered by a long-life (4-year) disposable battery. Automated tests help ensure readiness.
• Versatile: Available for use on anyone of any age, including children and infants.
• Effective: Patented SMART Analysis heart rhythm assessment and SMART Biphasic defibrillation therapy, clinically proven in nearly 10 years of use. No other biphasic waveform is as well documented.

Replaceable SMART Pads Cartridges

The cartridge contains two adhesive pads that are peeled and placed on the patient’s bare skin as indicated by the pictures on the pads. The pads are “smart” because they can sense that they have been removed from the cartridge and applied to the patient.
