Patent attributes
A medical device such as a defibrillator that incorporates corrective voice prompts that navigate users around operator errors. The voice prompts may, for example, address errors of readiness (e.g., failing to connect the defibrillator to an AC power source, failing to pre-connect electrodes, etc.), errors of omission (i.e., forgetting to do something, such as attempting to deliver a shock before the defibrillator is charged), and errors of commission (i.e., doing the wrong thing, such as attempting to shock VF when in the synchronization mode). The voice prompts may address errors in the delivery of therapy (e.g., attempting to shock VF when in the synchronization mode) or they may address errors other than in the delivery of therapy (e.g., failing to connect to an AC power source).
