WELCH ALLYN DEFIBRILLATOR
Malfunctioning Medical Devices Causing Injury
Welch Allyn Defibrillator Attorney
Defective Welch Allyn AEDs can experience unexpected shutdown and low defibrillation energy, among other defects. These malfunctions render the device unusable and could result in death. On December 15, 2008 the Welch Allyn AED 10 Automatic External Defibrillator (AED) and the MRL JumpStart AED were the subjects of a Class 1 recall due to chances of low defibrillation energy delivery, unexpected device shutdown and inadequate filtering of electromagnetic noise. Such conditions can prevent defibrillation of a person in cardiac arrest and can lead to death.
Class 1 recalls are the most serious type of recall and involve situations in which there is a reasonable probability that use of the product will cause serious injury or death.
About Malfunctioning Welch Allyn AEDs
These devices are used to treat adults suffering from cardiac arrest. Emergency or medical workers use the device to evaluate heart rhythms and electrically shock the heart in case of abnormal rhythms. The malfunctioning AEDs were manufactured from October 3, 2002 to January 25, 2007. A total of 14,054 defibrillators were recalled after 20 incidents of low defibrillation energy delivery, 8 incidents of inadequate filtering of electromagnetic noise and 11 incidents of unexpected device shutdown. According to Welch Allyn, notification of the recall was sent to U.S. and Canada customers February 2009 and other international customers were to receive notification later in March.
Low Defibrillation Energy Delivery
The AED 10 could unexpectedly shut down during use if the pads are attached to the patient before the device is turned on and the device is set to deliver an initial shock of 150 Joules energy. The user’s instructions on the back of the device and the Quick Reference guide advise against attaching the pads before turning on the device, however, some pages in the user’s manual include illustrations of the pads attached prior to turning on the device. Welch Allyn advises that you disregard the erroneous illustrations and plans to distribute corrected manuals. WARNING: Units sold outside the U.S. that have the British voice option have a default setting of 150 Joules initial shock. U.S. units have a factory default setting of 200 Joules. The combination of these conditions and ultimate shutdown of the device has resulted in one death. There are 10,735 devices that may have this defect. They were all manufactured between October 3, 2002 and December 30, 2004.
Inadequate Filtering of Electromagnetic Noise
The Welch Allyn AED 10 and MRL JumpStart could have electromagnetic noise interference, causing a shock to be delivered to a patient with a non-shockable rhythm. Simply, in the case of inadequate electromagnetic noise filtering, the device cannot decipher shockable rhythms and, therefore, misfires and fails to fire. There has been one incident in which this occurred and 7 incidents in which the device failed to recognize a shockable rhythm. 10,735 devices may have this defect. They were all manufactured between October 3, 2002 and December 30, 2004.
The AED 10 could fail due to blown F1 fuses. In such a case, the device would be inoperable and warning light would illuminate, alerting of the condition. A fuse could blow during use, which would cease defibrillation and possibly result in death. There are 4,568 devices that may have this defect. They were all manufactured between May 18, 2004 and December 30, 2004.
Shutdown in Cold Temperatures
If your device was upgraded with software version 02.06.00, there is a possibility it could shut down during use in cold temperatures. This would render the device inoperable and could result in death. There are 87 devices that may have this defect. They were all serviced in 2007.
Voice Prompt Failure
The AED 10 and MRL JumpStart could fail to deliver voice prompts due to discontinuous speaker connection. There have been 10 such incidents reported. There are 5,336 devices that may have this defect. They were all manufactured between October 3, 2002 and July 26, 2004.
