1. An external defibrillator, comprising:
- a battery;
defibrillation circuitry housed within an enclosure having an exterior, the defibrillation circuitry powered by the battery and includinga computer having programming to conduct autonomous, recurring self-tests, which include at least some portion of the defibrillation circuitry, and to perform a rescue, the self-tests capable of determining an operational status of the external defibrillator,a switch for a user to switch the external defibrillator from OFF to ON, wherein ON activates the defibrillation circuitry and its associated programming to perform a rescue, and OFF places the external defibrillation circuitry and its associated programming in a standby status permitting self-tests to be conducted but not a rescue; and
an active status indicator comprising a first light source that illuminates, the first light source operated by the programming running on the computer, wherein when the external defibrillator is OFF and the most recent self-test has determined that the external defibrillator operational status is normal, the first light source blinks frequently to indicate that the defibrillator is ready for use.

Abstract
An AED includes defibrillation circuitry housed within an enclosure, a first processor programmed to periodically test the operability of the defibrillation circuitry and a second processor in communication with the first processor. The AED further includes a visual indicator, such as a red/green LED, positioned at the exterior of the enclosure that is operatively connected to the second processor. The second processor is programmed to control the visual indicator in response to the periodic test results provided to it by the first processor.

9. An external defibrillator, comprising:
-
a battery; defibrillation circuitry housed within an enclosure having an exterior, the defibrillation circuitry powered by the battery and including a computer having programming to initiate and run recurring self-tests and to perform a rescue, each self-test including at least a portion of the defibrillation circuitry, the self-tests occurring at intervals and capable of determining an operational status of the external defibrillator, and a switch for a user to switch the external defibrillator from OFF to ON, wherein ON activates the defibrillation circuitry and its associated programming to perform a rescue, and OFF does not activate the defibrillation circuitry and its associated programming to perform a rescue but allows self-tests to be conducted; and an active status indicator comprising a first light source that illuminates, the first light source operated by the programming running on the computer, wherein when the external defibrillator is OFF and the most recent self-test has determined that the defibrillator requires maintenance, the first light source blinks frequently to indicate that the defibrillator requires maintenance. - View Dependent Claims (10, 11, 12, 13, 14, 15)
