Abstract

Disclosed is a method and computer program product for analyzing treatment of a sudden cardiac arrest victim. The method includes attaching the victim to an automatic external defibrillator, capturing treatment information about the CPR event, alerting a rescuer of treatment steps, and displaying a chest compression interface based on the treatment information. The chest compression interface may include an event log about various AED, rescuer, and background events and may be used to generate a graphical chest compression chart for simple analysis of the quality of a CPR treatment.

Claims

1. A method of analyzing treatment of a sudden cardiac arrest victim, the method comprising the steps of:

attaching the victim to an automatic external defibrillator;

capturing treatment information;

alerting a rescuer of treatment steps; and

displaying a chest compression interface based on the treatment information.

3. The method of claim 1, the step of alerting a rescuer comprising one or more of an audio alert, a visual alert, and a vibration alert.

4. The method of claim 1, the treatment steps comprising one or more of increasing chest compression pressure, decreasing chest compression pressure, varying a distance of a compression into a chest of the victim, and varying a distance of retraction from the chest of the victim.

5. The method of claim 1, further comprising the chest compression interface including a graphical representation of treatment information.

6. The method of claim 5, further comprising the chest compression interface including a patient identifier field, a date field, a time field, and an event table.

7. The method of claim 6, further comprising the chest compression interface including one or more of a cardiac arrest date field, arrest start time, and a rescue worker identifier.

8. The method of claim 6, further comprising providing a selectable CPR activity check box section to configure the event table to display one or more selected CPR activities.

9. The method of claim 8, further comprising a CPR activity being one or more of an event reported by the automatic external defibrillator, a presence of a chest compression, heart rhythm information, and a communication with an emergency services center.

10. The method of claim 9, further comprising the event table including a time column, event description column, and a chest compression rate value column.

11. The method of claim 10, further comprising the event table including a description column for entering an explanation for discontinuing each chest compression cycle.

12. The method of claim 6, further comprising the chest compression interface including a graphical chest compression chart.

13. The method of claim 12, further comprising deriving the chest compression chart based on data in the event table.

14. The method of claim 12, further comprising the chest compression chart including a number of colored segments, each colored segment corresponding to one of a chest compression, a pause by the automatic external defibrillator, a rescuer pause, a treatment pause, and a poor quality chest compression.

15. The method of claim 14, further comprising analyzing the chest compression chart to designate a quality designation for the treatment of the sudden cardiac arrest victim.

16. The method of claim 15, further comprising designating the treatment as a high quality treatment where the percentage of time chest compressions are administered are over a selected threshold.

17. The method of claim 16, further comprising the selected threshold being 50%.

18. The method of claim 15, further comprising using the quality designation for one or more of subsequent training of the rescuers, medical malpractice inquiries, determining insurance coverage, development shock algorithms, and aggregate statistical analysis.

19. The method of claim 1, further comprising transmitting the treatment information to a monitoring center.

20. The method of claim 19, further comprising the monitoring center transmitting treatment instructions to a rescuer based on the treatment information.

21. The method of claim 19 further comprising the monitoring center transmitting treatment instructions to a rescuer based on a chest compression chart derived from the treatment information.

2. The method of claim 2, the treatment information being one or more of a date, a time, a vital sign, an administration of a chest compression, an administration of medication, and an administration of ventilation.

22. A computer program product having program code stored thereon for analyzing a sudden cardiac arrest treatment, the program code, when executed on a computer, causing the computer to:

capture treatment information, alert a rescuer of treatment steps; and

display a chest compression interface based on the treatment information.

23. A system for analyzing a sudden cardiac arrest treatment, the system comprising:

an automatic external defibrillator, the automatic external defibrillator including a chest compression analysis module, a notification device, and a communications component;

the chest compression analysis module operative to capture treatment information, alert a rescuer of treatment steps; and

display a chest compression interface based on the treatment information.
