Cardiac Science Corp is initiating a voluntary field correction for certain automated external defibrillators (AEDs) manufactured between 2003 and 2009 that may fail to deliver therapy during a resuscitation attempt.

The company has received complaints concerning four resistors within certain AEDs manufactured between August 2003 and August 2009. AEDs produced since August, 2009 are unaffected.

Device failure may affect resuscitation of the patient, which could lead to serious adverse events or death.

A correction will be made available in May 2010. Until then, the company advises that customers check the status indicator on the front of the AED and follow all document procedures, but otherwise leave their AEDs in service.

However, if the AED is not rescue ready (the indicator is red) customers should contact the company immediately. For more information, see the full release on the Cardiac Science Web site.
