Welch Allyn AED 20

The Welch Allyn AED 20 is a safe, easy-to-use defibrillator for use by basic life support (BLS) personnel. It is light and mobile and can be used where several minutes could elapse before the arrival of advanced life support (ALS) personnel. When the Welch Allyn AED 20 is properly connected to a patient who is unconscious, not breathing, and unresponsive, the defibrillator analyzes the patient’s heart rhythm and determines whether a shockable situation exists and, if appropriate, arms the shock button.
