Patent ID: 8744574

Claim:
An external defibrillator comprising: an energy storage module configured to store an electrical charge; a defibrillation port configured to guide via electrodes stored electrical charge to a person; a processor configured to cause a verbal prompt to be issued to a rescuer using the defibrillator in connection with the defibrillator executing a protocol; and an interface configured to receive a muting input, in which if a first muting input is received via the interface, the verbal prompt is caused to not be issued even though the defibrillator is executing the protocol, in which the processor can cause at least two types of verbal prompts to be issued, in which receiving the first muting input causes one of the two types of verbal prompts to not be issued but still permits the other of the two types of verbal prompts to be issued, and in which receiving a second muting input causes the other of the two types verbal prompts to not be issued.
