For the ordinary person in the extraordinary moment, unsurpassed ease of use in 3 different published studies.^1,2,3

Available without a prescription⁴, the HeartStart OnSite Defibrillator is designed with innovative technology, based on extensive research and user feedback, that has produced a defibrillator so easy to use that 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 victim’s side.

Using clear, natural voice instructions, the HeartStart OnSite Defibrillator guides you through each step of defibrillation. Designed to not slow you down or leave you behind, it paces and adapts voice instructions to your actions every step of the way. It even reminds you to call emergency medical services (EMS). On-demand CPR Coaching helps the stressed user recall their training.

Ready when needed. Every meticulously built HeartStart OnSite Defibrillator goes through a 120 point test before it leaves the factory. On the job, the OnSite automatically conducts self-tests every single day, not just weekly. It performs over 80 different tests in all. Even the pads are tested for readiness.

Effective. The electric medicine delivered by the HeartStart OnSite is the most proven in the industry. Over 40 studies confirm its effectiveness. Philips’ high-current/low energy therapy ensures a potent defibrillation dose, while minimizing side effects that are harmful to a fragile heart. So the OnSite can deliver its most powerful therapy from the very first shock.

Make the most of CPR. Recent studies^5,6,7,8  have shown that CPR is even more vital to survival than previously realized. Yet its benefits dissipate in seconds. Delivering a shock quickly after chest compressions is critical. The HeartStart OnSite’s Quick Shock feature delivers therapy in just 8 seconds (typical) after chest compressions. Other devices can take 2 or 3 three times that, reducing the likelihood of shock success, and potentially, survival.

Give your early defibrillation program the best chance for success. With HeartStart Essentials AED Program Management Services (available in the US), Philips experts can draw on a wealth of experience to help you get your program started on the right foot, with pre-implementation consulting and site assessments. We can help manage your everyday needs, including medical direction from a licensed physician, AED/CPR training, web-based program management, and case management software.
