Contraindications for AED Therapy

An AED is not to be used on patients that exhibit one or any combination of the following:

Responsiveness

￿Spontaneous breathing

Palpable pulse

	Precautions for AED Therapy
	The AED algorithm is not designed to handle erratic spiking problems caused
	by a properly or improperly functioning pacemaker. In patients with cardiac
	pacemakers, the HeartStart XLT may have reduced sensitivity and not detect
	all shockable rhythms.
NOTE
	AED	mode is not intended for use on children less than 8 years of age. For
	children older than 8 years, the American Heart Association recommends that
	standard operating procedures for AEDs be followed. American Heart Asso-
	ciation Guidelines 2000 for Cardiopulmonary Resuscitation and Emergency

Indications for Manual Defibrillation Therapy

Asynchronous defibrillation is the initial treatment for ventricular fibrillation and ventricular tachycardia, in patients who are pulseless and unresponsive.

Synchronous defibrillation is indicated for termination of atrial fibrillation. The SMART Biphasic waveform utilized in the HeartStart XLT Defibrillator/Monitor has undergone clinical testing demonstrating its effectiveness for cardioversion of atrial fibrillation.

The SMART Biphasic waveform utilized in the HeartStart XLT has under- gone clinical testing in adults. These trials support the waveform’s effective- ness for defibrillation of ventricular tachyarrhythmias at 150J.

In manual mode operation, the HeartStart XLT incorporates some user select- able lower energy levels that were not used in the clinical trials.
