Abstract

A method for displaying time-correlated medical event data including the steps of: providing time-correlated event data to a display device; selecting a first event to be displayed; and displaying the first event together with a time-correlated second event on the display device. Another embodiment is a method for displaying time-correlated medical event data including the steps of: manually entering data comprising a first event into a display device; time-correlating the first event with data comprising a second event collected by a medical device; and displaying the first event together with the second event on the display device.

Claims

1. A method for displaying time-correlated medical event data comprising the steps of:

providing time-correlated medical event data to a display device,

selecting a first event from the time-correlated medical event data to be displayed;

displaying the first event; and

displaying a second event along with the first event on the display device in time-correlated manner, based on the selection of the first event, wherein at least one event is a continuous data stream.

2. The method of claim 1 wherein the providing step comprises connecting a memory device to the display device.

3. The method of claim 1 wherein the providing step comprises using the display device to collect time-correlated event data.

4. The method of claim 1 wherein the providing step comprises providing time-correlated event data collected by a medical device and user-entered event data, wherein the user-entered event data is time-correlated with the event data collected by the medical device.

5. The method of claim 1 wherein the second event is patient ECG data, the displaying step comprising displaying the first event together with at least a portion of the ECG data correlating in time with the first event.

6. The method of claim 5 wherein the displaying step further comprises displaying a marker together with the patient ECG data, the marker representing the first event.

7. The method of claim 6 wherein the marker comprises a caption.

8. The method of claim 1 wherein the selecting step comprises selecting the first event from a list of events.

9. The method of claim 1 wherein the selecting step comprises selecting the first event from a list of events displayed on the display device.

10. The method of claim 1 wherein the selecting step comprises entering a unique identification of the first event into the display device.

11. The method of claim 1 wherein the providing step comprises providing time correlated event data collected by a defibrillator, and further wherein the second event comprises patient ECG data.

12. The method of claim 11 wherein the first event comprises delivery of a shock by the defibrillator to a patient.

13. The method of claim 1 wherein the providing step comprises providing time-stamped event data.

14. A method for displaying time-correlated medical event data comprising the steps of:

manually entering data comprising a first event into a display device;

time-correlating the first event with data comprising a second event collected by a medical device; and

displaying the resulting time correlated first event and second event together on the display device.

15. The method of claim 14 further comprising creating a list comprising a first entry corresponding to the first event.

16. The method of claim 15 further comprising selecting the first entry from the list prior to the displaying step.
