Defibrillator Event Data with Time Correlation
First Claim
Patent Images
1. A defibrillator system including a defibrillator which analyzes a heartbeat and determines whether a defibrillating shock is to be delivered, including an ECG data analyzer and a high voltage shock delivery circuit comprising:
- a data storage medium which stores data concerning operation of the defibrillator together with elapsed time data associated with the operation data; and
a wireless transmitter, coupled to the data storage medium, by which the operation data and time data are transmitted; and
an event data recorder, including a wireless receiver, which executes a control program for the reception and storage of the transmitted operation data and time data, the event data recorder including a converter operable to convert the elapsed time data to an absolute time base of the event data recorder.

Abstract
A defibrillator records event data with an elapsed time marker. Upon transfer of the event data to an event data recorder the elapsed time markers are used to time-stamp the event data with actual location time. The event date can be analyzed with a display of both elapsed time and actual location time.

8. A defibrillator system including a defibrillator which analyzes a heartbeat and determines whether a defibrillating shock is to be delivered, including an ECG data analyzer and a high voltage shock delivery circuit, the defibrillator further including a data storage medium which stores data concerning operation of the defibrillator together with time data associated with the operation data;
- and
an event data recorder which is responsive to the reception of operation data and time data from the defibrillator, the event data recorder including a time-stamp responsive to the time data for time-stamping received operation data to the time base of the event data recorder; and a communication link, which is operable to communicate data between the defibrillator and the event data recorder. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for correlating cardiac event data stored by an AED to an absolute time base comprising:
-
putting the AED in communication with an event data recorder; transmitting event data and associated elapsed time data from the AED to the event data recorder; converting at least one piece of the elapsed time data to an absolute time base in the event data recorder; and displaying the event data with associated absolute time data. - View Dependent Claims (16, 17, 18, 19)
