Abstract
A system for automatically synchronizing, isolated clocks is disclosed. In the preferred embodiment, the internal clock of an automated external defibrillator (AED) or an external defibrillator (ED) is integrated with a radio broadcast to receive standard time. The system may also include a mechanism for synchronizing the clock or a computer tracking the time of emergency calls such as 911. Further, the system enables synchronization between the AED or ED internal clock and the 911 clock such that response times can be accurately determined.
Claims12
A method of recreating a historical time sequence in order to monitor and evaluate response time in a life critical cardiac intervention evolution, the intervention being carried out by at least two independent caregivers, the independent caregivers not relying on organizational or technical continuity or compatibility, comprising the steps:
- correcting an automated electronic defibrillator (AED) clock by matching a standard time radio broadcast;
- time correcting intervention data stored in an AED memory;
- downloading time-corrected intervention data stored in the AED memory to a computer;
- correcting a clock of an emergency caregiver data storage means by matching a standard time radio broadcast, as needed;
- merging the time-corrected AED intervention data and the time-corrected emergency caregiver data in the computer;
- and
- recreating a historical time sequence of the intervention by comparing the time-corrected AED intervention data and the time-corrected emergency caregiver data.
