Available without a prescription,4 the HeartStart OnSite Defibrillator is designed with innovative technology, based on extensive research and user feedback, that has produced a defibrillator so easy to set up and 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. Philips pioneered the use of biphasic waveforms in external defibrillators. The electric medicine delivered by the HeartStart OnSite has been rigorously studied, with more than 40 studies demonstrating high first shock efficacy and effectiveness across the full spectrum of patients. Philips SMART Biphasic therapy uses a unique combination of high current to maximize effectiveness and a lower energy dose to minimize side effects that are harmful to a fragile heart. The result – the HeartStart OnSite delivers its maximum shock strength starting with the 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 OnSites 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.The HeartStart OnSite Ready-Pack configuration arrives to you virtually ready-to-rescue out of the box, with device pre-installed in carry case, and battery and pads pre-installed in the device.  The Ready-Pack is designed to be the simplest-to-deploy AED, giving you the peace of mind that it is deployed correctly, with less effort.  The simple and welcoming set-up and maintenance instructions are designed to take the intimidation out of owning a defibrillator.With HeartStart AED Services Program Management (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.

Product Specifications Defibrillator Number: HeartStart M5066A Defibrillator Family: HS1 How Supplied: Defibrillator, battery (one, preinstalled), SMART Pads (one, preinstalled), Set-up/Maintenance guide with expiration date tags, Owner’s Manual, Quick Reference Guide. HeartStart Onsite (HS1) Ready-Pack option R01: Defibrillator inside carry case, battery (one, pre-installed), SMART Pads (one set pre-installed plus spare set in carry case), Set-up/Maintenance guide with expiration date tags, Owner’s Manual, Quick Reference Guide. Waveform Truncated Exponential Biphasic. Waveform parameters adjusted as a function of each patient’s impedance. Therapy Adult defibrillation peak current: 32A (150J nominal) into a 50 ohm load. Pediatric defibrillation (with optional Infant/Child SMART Pads Cartridge): 19A (50J nominal) into a 50 ohm load. Shock-to-Shock Cycle Time Typically less than 20 seconds between shocks in a series. Quick Shock Able to deliver a chock after the end of a CPR interval, typically in eight seconds. Voice Instructions Detailed voice messages guide responder through use of the defibrillator. CPR Coaching Instructions for adult and infant/child CPR available at user’s option. Shock Delivery Via adhesive pads placed on patient’s bare skin as illustrated on pads. Controls Green SMART Pads cartridge handle, green On/Off button, blue i-button, orange Shock button Indicators Ready light; blue i-button; caution light Physical Requirements Sealing Solid objects per EN60529 class IP2X Drip-proof per EN60529 class IPX1 Temperature Operating: 32º – 122º F (0º – 50º C) Standby: 50º – 109º F (10º – 43º C) Humidity Operating: 0% to 95% relative, non-condensing Standby: 0% to 75% relative, non-condensing Altitude Operating: 0 to 15,000 ft (0 to 4,500 m) Standby: 0 to 8,500 ft > 48 hours and 8,500 to 15,000 feet < 48 hours Shock/Drop Abuse Withstands 1 meter drop to any edge, corner or surface. Vibration Meets EN1789 random and swept sine, road ambulance specification in operating and standby states. EMI (Radiated/ Immunity) Meets EN55011 Group 1 Level B Class B and EN61000-4-3. Patient Analysis System Patient Analysis Evaluates patient ECG to determine if a rhythm is shockable. Rhythms considered shockable are ventricular fibrillation (VF) and certain ventricular tachycardias (VT) associated with lack of circulation. For safety reasons, some VT rhythms associated with circulation will not be interpreted as shockable, and some very low-amplitude or low-frequency rhythms will not be interpreted as shockable VF. Sensitivity/ Specificity Meets AAMI DF80 guidelines and AHA recommendations for adult defibrillation (Circulation 1997;95:1677-1682). Artifact Detection The effects of pacemaker artifact and electrical noise are minimized with artifact detection.
