Each year sudden cardiac arrest (SCA) strikes approximately 340,000 people in the U.S. alone and hundreds of thousands more worldwide. 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 hearts normal pumping rhythm. A victim’s best chance of surviving SCA is to receive that shock within 5 minutes of collapse.
Philips HeartStart “On-Site” Defibrillators designed the HeartStart OnSite Defibrillator for the ordinary person in the extraordinary moment.
The 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 sense and adapts to your actions every step of the way.
HeartStart OnSite includes proven Philips technologies for heart rhythm assessment and defibrillation energy delivery. And like all HeartStart defibrillators, it can be used to treat infants, children and adults.
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 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 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.
