Device Use

Automatic external defibrillators (AEDs) are used to deliver lifesaving electrical shocks to people with sudden cardiac arrest, a medical condition in which the heart suddenly and unexpectedly stops beating.  Defibrillation electrodes are connected to the AED to help the device analyze a patient’s heart rhythm and deliver an electrical shock to restore normal heart rhythm when needed. The primary users of AEDs are first responders and hospital health care providers.


Reason for Recall

The Leonhard Lang defibrillation electrode is being recalled due to a connector compatibility issue with the Welch Allyn AED model 10. The user may not be able to connect the electrodes to the defibrillator when a shock is needed. This may result in a delay in delivering the electrical therapy needed to revive a patient in cardiac arrest.

A delay in therapy could result in serious patient injury and/or death.

Who May be Affected

  • Health care providers and first responders using this defibrillation electrode
  • Patients who may need this defibrillation electrode to restore normal heart rhythm
