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 adults, as well as infants and children4.

Ready When Needed

HeartStart OnSite is powered by a simple, long-life (four-year) battery, the same technology used with confidence in millions of 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, the OnSite has passed its last self-test and you can be confident the HeartStart OnSite is ready for use. If a self-test finds that 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.

Easy to Use

Using the HeartStart OnSite Defibrillator is simple. Pulling the green handle activates the defibrillator and 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.

• If a shock is indicated, 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 indicated, 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.
