AED 10 User Manual - Welch Allyn

26 Using the defibrillator Welch Allyn AED 10 Automated External DefibrillatorOverviewTrained operatorsThe Welch Allyn AED 10 is capable of operating in an automated mode. In this mode, theoperator must be trained to use the unit and understand the indications andcontraindications for use.The Welch Allyn AED 10 is intended to treat patients in cardiopulmonary arrest. It is foruse in either in-hospital or out-of-hospital arrests. It is intended that the operator isauthorized by a physician/medical director, and has the following training skills:• American Heart Association Heartsaver course, American Red Cross CPR/AEDcourse, NSC CPR and Rescuer Course, or equivalent.• Training in the use of the Welch Allyn AED 10.Fibrillation and defibrillationOrdinarily the heart produces regular electrical activity—normal sinus rhythm (NSR).Fibrillation is an abnormal heart rhythm that replaces the normal rhythmic contraction ofthe heart. During fibrillation, irregular cardiac electrical activity causes rapid,uncoordinated twitching movements. As a result, the heart cannot pump blood effectivelycausing a lack of appropriate circulation and pulse.Defibrillation is the delivery of a brief, high-energy pulse of electricity to the heart muscleusing a device called a defibrillator. Early defibrillation increases the potential to restorethe normal cardiac electrical activity and allow the heart's natural pacemaker areas toregain normal function.The Welch Allyn AED 10, using direct current, applies a brief, high-energy pulse ofelectricity to the heart to counteract fibrillation of the heart muscle and restore a normalheartbeat.The Welch Allyn AED 10 will only administer a defibrillation pulse to a patient exhibiting ashockable cardiac rhythm. Shockable rhythms are described in “Rhythm recognitionperformance” on page 81. All other rhythms are determined “non-shockable” and thepatient is not a candidate for defibrillation. Cardiopulmonary resuscitation (CPR),medication, and supplemental oxygen may also be required to effectively resuscitate thepatient.
