WASHINGTON (AP) -- Welch Allyn is recalling about 14,000 external defibrillators after 39 reported incidents, including two that involved patient deaths.

The recall, announced Tuesday, involves 14,054 AED 10 and MRL JumpStart external defibrillators made between Oct. 3, 2002, and Jan. 25, 2007. The Beaverton, Ore., company says there is a remote chance the devices, available through prescription, may produce low-energy shock, shutdown unexpectedly or be susceptible to electromagnetic noise interference.

The issues might prevent defibrillation of a patient in cardiac arrest and could lead to death, the company said in a statement. The company had received 20 instances of low-energy shock, eight instances of electromagnetic noise interference, and 11 instances of the device unexpectedly shutting down.

To the company's knowledge, the defects of the device did not contribute to the two deaths, said spokesman Jamie Arnold. "Human factors played a role in each incident: damaged device in one and failure to follow directions in the other," he said in an e-mail.

The company said customers should keep AED 10 or MRL JumpStart units in use until they receive replacements because the chance of malfunction is low.

In October 2007, the company announced another recall of 1,794 AED10 automatic external defibrillators. The devices could fail or produce a delay in analyzing a patient's ECG and may not deliver appropriate therapy. This could result in failure to resuscitate the patient. No injuries associated with this product had been reported, but the company had reported 49 failures during internal testing and had received three customer complaints.
