* Automated External Defibrillator
From Wikipedia, the free encyclopedia
An automated external defibrillator or AED, is a portable electronic device that automatically diagnoses the potentially life threatening cardiac arrhythmias of ventricular fibrillation and ventricular tachycardia in a patient and is able to treat them through defibrillation - the application of electrical therapy which stops the arrhythmia, allowing the heart to reestablish an effective rhythm. With simple audio and visual commands, AEDs (defibrillators) are designed to be simple to use for the layman, and the use of AEDs (defibrillators) is taught in many first aid, first responder, and basic life support courses.
Effect of Delayed Treatment
Uncorrected, these cardiac conditions (ventricular tachycardia, ventricular fibrillation, asystole) rapidly lead to irreversible brain damage and death. After approximately three to five minutes, irreversible brain/tissue damage may begin to occur. For every minute that a person in cardiac arrest goes without being successfully treated (by defibrillation), the chance of survival decreases by 7 percent per minute in the first 3 minutes, and decreases by 10 percent per minute as time advances beyond ~3 minutes.
Requirements for use
AEDs (defibrillators)are designed to be used by laypersons who ideally should have received AED (defibrillators) training. This is in contrast to more sophisticated manual and semi-automatic defibrillators used by health professionals, which can act as a pacemaker if the heart rate is too slow (bradycardia) and perform other functions which require a skilled operator able to read electrocardiograms.

AED Defib Technology
This is too important not to choose the best!
Defibrillators save lives
Cardiac Science's proprietary RHYTHMx™ Software and STAR® Biphasic Waveform provide
effective technology solutions to treat sudden cardiac arrest.
RHYTHMx Technology is 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 customised defibrillation energy for the patient based on the
patient's impedance. The patented RescueReady® technology ensures your AED can be
counted on when you need it most - during a rescue.

RescueReady Technology®
Ensuring reliable AED Defibrillator operation
One of the most important features of a Cardiac Science AED Defib 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.

RHYTHMx™ Technology
Making 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 recognises a rhythm change, the Cardiac Science device automatically disarms,
informs the user that that the rhythm has changed, and reanalyses 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.
- Synchronised shock - RHYTHMx technology automatically synchronises shock delivery
whenever possible to the patient's electrocardiogram R-wave. If unable to synchronize
it will deliver an unsynchronised shock. Synchronisation 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
Saving minutes saves lives
There are a number of ways an AED Defib 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. The Cardiac Science methodology is that no two patients
are alike. That's why Cardiac Science has introduced the proprietary STAR Biphasic
technology, providing escalating biphasic energy and customised, 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 customised 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 Defib, a medical director can
customise 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.
