STAR® Biphasic Waveform Technology
There are a number of ways an AED can deliver a defibrillation shock. Some AEDs provide the same level of energy each time a shock is delivered. Other AEDs deliver higher levels of energy with each shock, but still administer the same energy level for every patient. Cardiac Science believes no two patients are alike. That's why Cardiac Science's introduced the proprietary STAR Biphasic technology, providing escalating biphasic energy and customized, variable energy.

-
STAR Biphasic technology measures a patient's impedance (the body's opposition to the flow of electrical current), adjusts defibrillation parameters, and delivers an energy level customized to the needs of that patient.
-
STAR Biphasic escalates energy over a range of impedances. This proven method of escalating energy is consistent with American Heart Association guidelines and is well established in the defibrillation industry.
-
STAR Biphasic Waveform has the highest reported effectiveness in hospital and pre-hospital data.
-
In clinical trials, STAR Biphasic was 100% effective at defibrillating patients in ventricular fibrillation-the most common arrythmia of sudden cardiac arrest on the first shock.
-
Pre-hospital data for STAR Biphasic has shown defibrillation success rates of 89 percent with an average number of 2.3 shocks per patient.
-
If using MDLink Software with the Powerheart AED G3, a medical director can customize parameters to follow a desired defibrillation rescue protocol. Adjustable parameters include 5 defibrillation energy protocols such as ultra low, standard and non-escalating variable energy options.
Products with the STAR Biphasic Technology include:
- Powerheart AED G3
- FirstSave AED G3
- Powerheart CRM Cardiac Rhythm Module
