22 Using the Defibrillator

Overview

The Welch Allyn AED 10 is capable of operating in an automated mode. In this mode, the
operator must be trained to use the unit and understand the indications and
contraindications for use.

Trained Operators

The Welch Allyn AED 10 is intended to treat patients in cardiopulmonary arrest. It is for
use in either in-hospital or out-of-hospital arrests. It is intended that the operator is
authorized by a physician/medical director, and has the following training skills:
• American Heart Association Heartsaver course, American Red Cross CPR/AED
course, NSC CPR and Rescuer Course, or equivalent.
• Training in the use of the Welch Allyn AED 10.

Fibrillation and Defibrillation

Ordinarily the heart produces regular electrical activity—normal sinus rhythm (NSR).
Fibrillation is an abnormal heart rhythm that replaces the normal rhythmic contraction of
the heart. During fibrillation, irregular cardiac electrical activity causes rapid,
uncoordinated twitching movements. As a result, the heart cannot pump blood effectively
causing a lack of appropriate circulation and pulse.
Defibrillation is the delivery of a brief, high-energy pulse of electricity to the heart muscle
using a device called a defibrillator. Early defibrillation increases the potential to restore
the normal cardiac electrical activity and allow the heart's natural pacemaker areas to
regain normal function.
The Welch Allyn AED 10, using direct current, applies a brief, high-energy pulse of
electricity to the heart to counteract fibrillation of the heart muscle and restore a normal
heartbeat.
The Welch Allyn AED 10 will only administer a defibrillation pulse to a patient exhibiting a
shockable cardiac rhythm. Shockable rhythms are described in Appendix A. All other
rhythms are determined "non-shockable" and the patient is not a candidate for
defibrillation. Cardiopulmonary resuscitation (CPR), medication, and supplemental oxygen
may also be required to effectively resuscitate the patient.
