Better, Faster, More Capable Defibrillation Technology
Cardiac Science's proprietary
RHYTHMx® Software and STAR® Biphasic Waveform
provide effective technology solutions to treat sudden
cardiac arrest. Cardiac Science developed RHYTHMx®
Technology, a patented software detection algorithm
to accurately and instantly detect abnormal heart rhythms,
determine if they are life threatening and when appropriate,
facilitate delivery of a live-saving defibrillation
shock. The STAR® Biphasic Waveform Technology was
developed with each individual's needs in mind, providing
customized defibrillation energy for the patient based
on the patient's impedance. Cardiac Science's patented
RescueReady® technology ensures your Cardiac
Science AED can be counted on when you need it most
- during a rescue.

RHYTHMx® Technology
- Makes Hard Decisions Fast
The RHYTHMx® technology offers the most advanced,
smartest software analysis algorithm in the industry.
The RHYTHMx® technology is the intelligence behind
the Cardiac Science's
Powerheart hospital and public access defibrillation
products, and is designed to continuously monitor,
detect, and advise defibrillation therapy to treat cardiac
arrhythmias. |
• Specificity and Sensitivity - clinical results
with the RHYTHMx® technology demonstrated 100% sensitivity
(correct identification of shockable rhythms) and 99.4%
specificity (correct identification of non-shockable
rhythms).
• RHYTHMx® technology differentiates between
shockable life-threatening cardiac rhythms such as
ventricular arrhythmias (VT/VF) and supraventricular
tachyarrhythmias (SVT), plus distinguishes non-shockable
cardiac arrhythmia events.
• Non-committed device - If the RHYTHMx®
technology detects a shockable rhythm and charges,
but recognizes a rhythm change, the Cardiac Science
device automatically disarms, informs the user that
that the rhythm has changed, and reanalyzes the patient's
heart rhythm.
• Post-resuscitation monitoring - RHYTHMx®
technology continues to monitor the patient's heart
rhythm post resuscitation, to instantly detect the
reoccurrence of a life-threatening arrhythmia. If
cardiac arrest recurs, the Cardiac Science device
will charge automatically and advise the operator
to deliver a defibrillation shock.
• Synchronized shock - RHYTHMx® technology
automatically synchronizes shock delivery whenever
possible to the patient's electrocardiogram R-wave.
If unable to synchronize it will deliver an unsynchronized
shock. Synchronization of a defibrillation shock has
been shown to be more effective in converting patients
out of life threatening arrhythmias.
• RHYTHMx® Technology that allows a medical
director or physician to pre-program detection rates
for shockable cardiac arrhythmias such as VF, VT and
SVT. |

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 arrhythmia 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. |

RescueReady® Technology - Ensuring Reliable
AED Operation
One of the most important features of Cardiac Science
AEDs is its high degree of reliability. Performing the
most comprehensive self-testing in the industry ensures
Cardiac Science AEDs
are "RescueReady" when you need it. When
the green RescueReady indicator is lit, Cardiac Science
AEDs can be counted on to perform during a rescue.
|
| • Proprietary RescueReady® Technology tests
battery, system components, and verifies that the pre-connected
disposable electrodes can properly deliver a shock.
• Daily, weekly, monthly testing of battery,
electronics, and pre-connected electrodes occurs automatically.
• Once a month, the AED performs an automatic
full charge test of the high voltage circuitry, to
confirm the AED's ability to deliver a shock when
needed.
• RescueReady status indicator on the AED
handle changes from green/red and emits an audible
alert if service is required. (Powerheart
AED G3 only)
• Pre-connected electrodes are always stored
inside the device, eliminating confusion and possible
errors during a rescue.
• Patented RescueReady® technology confirms
the electrodes are in the AED and ready for use. |
