Welch Allyn AED 20®, Automatic External Defibrillator, part number 972200E. A total of 597 were manufactured between February and July 2004 which are subject to the recall.


Automatic external defibrillators are intended to be used for the treatment of cardiac arrest. The defibrillators are intended to deliver a shock to the heart to restore normal heart rhythm.

Reason for Recall:

The affected AED is susceptible to malfunction which may in some cases prevent the AED from delivering a shock and thus, result in a delay in treatment or death of a viable patient. This recall was initiated after receipt of a complaint of malfunction during clinical use that resulted in a death in Canada . The malfunction occurs when impact to the exterior of the AED20 causes an internal electrical short resulting in the AED20 failing to analyze the patient’s heart function. When this malfunction occurs during clinical use, the AED20 displays a “Defib Comm” error message on the device display.

Public Contact:

Consumers with questions may contact the company at 1-847-520-0300, Ext. 153.
