HeartStart OnSite Defibrillator -- Philips (M5066A)


Philips HeartStart OnSite Defibrillator (M5066A) - Shopping for a reliable and portable defibrillator for use in a school, gym, multi-family housing complex or corporate facility? Philips designed the HeartStart OnSite AED, or Automated External Defibrillator, for the ordinary person in the extraordinary moment. Our innovative technology, based on extensive research and user feedback, has produced a self-guiding 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.


  • A long battery shelf life of 5 years and 4 years installed life.
  • The same battery techonology used with confidence in millions of cameras.
  • Daily self-tests help ensure continued readiness.
  • A self-test also verifies that the pad cartridge is installed and in working order.
  • A blinking green "ready" light means the OnSite has passed its last self-test, so you can be confident the defibrillator is ready for use.



  • Using the 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 each pad on the patient to delivering a defibrillation shock.


Voice instructions guide you through the process:
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).

Battery and Self-tests:
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.

Infants and Children:
All HeartStart defibrillators can be used to treat infants and children using the optional Infant/Child SMART pads cartridge. OnSite senses when the infant/child cartridge is installed and automatically adjusts to a lower enery level more appropriate for infants and children, and also provides coaching for performing infant/child CPR.

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.
