The First Defibrillator Available Without a Prescription to Commercial Users

Philips, the leader in portable defibrillation innovation, designed the HeartStart OnSite Defibrillator for the ordinary person in the extraordinary moment. The first commercial defibrillator without a prescription, the OnSite is designed to be the easiest to use and most reliable defibrillator available. The innovative technology, based on extensive research and user feedback, has produced a defibrillator so easy-to-use that you can potentially save the life of a coworker, friend, or anyone else stricken with sudden cardiac arrest. Weighing just 3.3 pounds, this small and lightweight defibrillator can be easily carried to the victim’s side. Using clear, calm voice instructions, the OnSite Defibrillator guides you through each step of defibrillation, including CPR coaching. Integrated SMART pads placed on the victim’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 and children as well as adults.

Self-Test Ensures Readiness:

  • Daily self-tests check electrical components, subsystem sand battery
  • Self-test also verifies that the pads cartridge is installed and in working order
  • Blinking green “Ready” light means the OnSite has passed its last self-test, so you can be confident the defibrillator is ready for use

Long Battery Life:

  • 5-year shelf life plus 4-year installed life
  • Same battery technology used with confidence in millions of cameras


Using the HeartStart 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.

Optional infant pads available. Contact Darley for details.
