Welch Allyn AED 10™ Automatic External Defibrillators

Class 1 Recall
Date Recall
October 26, 2007

Welch Allyn AED 10™ Automatic External Defibrillators, manufactured between March 29, 2007 and August 9, 2007, part numbers 970302E, 970308E, 970309E, 970310E, and 970311E



These devices are used by emergency or medical personnel, or by others who have taken the appropriate training to use an AED10™ automatic external defibrillator. These devices are intended to treat adults in cardiopulmonary arrest (heart attack). They analyze an unconscious patient’s heart rhythm and automatically deliver an electrical shock to the heart if needed to restore normal heart rhythm.


Recalling Firm:

Welch Allyn Protocol, Inc.
8500 Sw Creekside Pl
Beaverton, OR 97008


Reason for Recall:

There is a possibility that these recalled devices may experience failure or unacceptable delay in analyzing a patient’s ECG resulting in possible failure to deliver the appropriate therapy. The possible failure or delay depends on the location of the defective part that stores an electrical charge on the circuit board.
