SECTION 2 - INTRODUCTION

OVERVIEW

This section presents information about the AED, its use, and the training requirements for operation.

Topic Page #

AED Description 15 Indications for Use 15 RHYTHMx AED ECG Analysis Algorithm 16 Rescue Protocol 18 STAR Biphasic Waveform 18 STAR Biphasic Energy Protocols for Responder AED 18 Operator Training Requirements 20

AED DESCRIPTION

The AED is a self-testing, battery-operated automated external defibrillator (AED). After applying the AED’s electrodes to the patient’s chest, the AED automatically analyzes the patient’s electrocardiogram (ECG) and advises the operator to push the button and deliver a shock if needed. The AED uses one button and guides the operator through the rescue using a combination of voice prompts, audible alerts, and visible indicators.

INDICATIONS FOR USE

The AED with STAR Biphasic Waveform is intended to be used by personnel who have been trained in its operation. The operator should be qualified by training in basic life support, CPR/AED or other physician-authorized emergency medical response. The device is indicated for emergency treatment of victims exhibiting symptoms of sudden cardiac arrest who are unresponsive and not breathing. If the victim is breathing post-resuscitation, the AED should be left attached to allow for acquisition and detection of the ECG rhythm. If a shockable ventricular tachyarrythmia recurs, the device will charge automatically and advise the operator to deliver therapy.

When the patient is a child under 8 years of age or weighs less than 55 lbs (25kg), the AED should be used with the Model 9730 Pediatric Attenuated Defibrillation Electrodes. Therapy should not be delayed to determine the patient’s exact age or weight.

Section 2 - Introduction

201-9198-001 Rev A

RHYTHMX®AED ECG ANALYSIS ALGORITHM

The RhythmX AED ECG analysis algorithm provides superior ECG detection capabilities, allowing it to be placed on patients at risk for sudden cardiac arrest. The features available with the AED include the following:

• Detection Rate

• Asystole Threshold

• Noise Detection

• Non-Committed Shock

• Synchronized Shock

• Pacemaker Pulse Rejection

• SVT Discriminators

• Supraventricular Tachycardia (SVT) Rate

• Continuous Monitoring

DETECTION RATE

All ventricular fibrillation (VF) and ventricular tachycardia (VT) rhythms at or above this rate will be classified as shockable. All rhythms below this rate will be classified as non-shockable. This rate is programmable between 120 bpm (beats per minute) and 240 bpm via MDLink Software by the Medical Director. The default Detection Rate is 160 bpm. The Responder AED detection rate is 160 bpm.

ASYSTOLE THRESHOLD

The asystole peak-to-peak threshold is set at 0.08 mV. ECG rhythms at or below 0.08 mV will be classified as Asystole and will not be shockable.

NOISE DETECTION

The AED will detect noise artifact in the ECG. Noise could be introduced by excessive moving of the patient or electronic noise from external sources like cellular and radiotelephones. When noise is detected, the AED will issue the prompt “

ANALYSIS INTERRUPTED. STOP PATIENT MOTION

” to warn the operator. The AED will

then proceed to reanalyze the rhythm and continue with the rescue.

NON-COMMITTED SHOCK

After the AED advises a shock, it continues to monitor the patient ECG rhythm. If the patient’s rhythm changes to a non-shockable rhythm before the actual shock is delivered, the AED will advise that the rhythm has changed and issue the prompt “

RHYTHM CHANGED. SHOCK CANCELLED.

” The AED will override the charge

and continue ECG analysis.

SYNCHRONIZED SHOCK

The AED is designed to synchronize shock delivery on the R-wave. The AED will automatically attempt to synchronize to the R-wave. If delivery cannot be synchronized within one second, a non-synchronized shock will be delivered.

PACEMAKER PULSE DETECTION

The AED contains pacemaker pulse detection circuitry to detect pulses from an implanted pacemaker.

SVT DISCRIMINATORS

The Responder AED is supplied with the SVT Discriminator enabled and with the default setting "NO THERAPY FOR SVT". With the factory default setting of "NO THERAPY FOR SVT", the Responder AED will not shock an SVT rhythm.

SVT Discriminators are sophisticated filters that analyze the morphology of the ECG waveforms and distinguish VF/VT from SVT and Normal Sinus Rhythms (NSR). The SVT Discriminator will only be applied to rhythms that fall between the Detection Rate and the SVT Rate. The factory default setting for this feature is "NO THERAPY FOR SVT", however the Medical Director can enable this feature using MDLink on the Responder AED.

SVT RATE

All rhythms with rates between the Detection Rate and SVT Rate will be screened through a number of SVT Discriminators to classify them into VF/VT or SVT. Rhythms classified as SVT between the two set rates are not shockable. All SVT rhythms above the rates will be classified as shockable. The SVT Rate must be greater than the Detection Rate and is selectable between 160 and 300 bpm or, “NO THERAPY FOR SVT” can be selected via MDLink Software by the Medical Director on the Responder AED only.

CONTINUOUS MONITORING

Responder AEDs are supplied with the Continuous Monitoring disabled. This is the factory default setting.

The Responder AED can monitor the ECG rhythms continuously throughout the rescue including during Charge and CPR mode. Continuous Monitoring will interrupt CPR if a shockable rhythm is detected. When CPR is interrupted, the prompt, “DO NOT TOUCH PATIENT. ANALYZING RHYTHM” will be issued. Only one false interruption will be allowed during a single rescue cycle. CPR mode will not be interrupted if preceded by three consecutive shocks. The factory default setting for Continuous Monitoring in CPR is disabled, however the Medical Director can enable/disable this feature via MDLink software.
