HeartStart Benefits
Lightweight: Fully equipped at just 3.3 pounds.
Intuitive: Clean design and clear voice instructions instill the confidence that’s needed when administering therapy to a person in cardiac arrest.
Every-Ready: Powered by a long life (4-year) disposable battery. Automated tests help ensure readiness.
Versatile: Available for use on anyone of any age, including children and infants.
Effective: Patented SMART Analysis heart rhythm assessment and SMART Biphasic defibrillation therapy, clinically proven in nearly 10 years of use. No other biphasic waveform is as well documented.
Easy to Use
Using the HeartStart OnSite Defibrillator is simple. Pulling the green handle powers-up the defibrillator and activates 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.

HeartStart OnSite determines if a shock is needed, based on its automated assessment of the victim’s heart rhythm:

If a shock is needed, 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 needed, 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.

Replacable SMART Pads Cartridges
The cartridge contains two adhesive pads that are peeled and placed on the patient’s bare skin as indicated by the pictures on the pads. The pads are “smart” because they can sense that they have been removed from the cartridge and applied to the patient.

HeartStart OnSite can be used on patients of any age. Special Infant/Child SMART Pads reduce the defibrillator’s shock energy, so that you can treat an infant or child suffering sudden cardiac arrest. The Infant/Child Pads cartridge is marked with an indication of the appropriate weight and with a teddy bear icon for ready identification.

To practice your skills, a special training pads cartridge (adult or infant/child) can be installed in the defibrillator. It suspends the defibrillator’s ability to shock, while walking you through patient care scenarios.

Defibrillator

Temperature Operating:
32? – 122?F (0? – 50?C)
Standby: 50º – 109?F (10? – 43?C)
Humidity Operating:
0% to 95% relative, non-condensing
Standby: 0% to 75% relative, non-condensing
Altitude:
Operating: 0 to 15,000 feet
Standby: 0 to 8,500 feet > 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. Battery (M5070A) Type: Volt DC, 4.2 Ah, composed of disposable long-life lithium manganese dioxide primary cells. Capacity: Minimum 200 shocks or 4 hours of operating time (EN 60601-2-4:2003) Install-by Date: Battery is labeled with an install-by date of at least five years from date of manufacture. Standby Life: Four years typical when battery is installed by the install-by date. (Will power the AED in standby state within the specified standby temperature range, assuming one battery insertion test and no defibrillation uses.) SMART Pads Adult SMART Pads Cartridge: M5071A defibrillation pads for patients 8 years of age and older or 55 lbs (25 kg) and over. Infant/Child SMART Pads Cartridge: M5072A defibrillation pads for patients under 8 years of age or 55 lbs. (25 kg). Rx only.
