Abstract

An external defibrillator is customized for at least one person, i.e., an anticipated patient, through creation of a profile for the anticipated patient that allows the defibrillator and users of the defibrillator to provide customized treatment to the patient. The profile may include treatment parameters for the anticipated patient, such as defibrillation therapy parameters selected for the patient. The profile may also include a baseline recording of a physiological parameter of the patient, and medical history and personal information regarding the patient. In some embodiments, the external defibrillator stores a profile for each of one or more anticipated patients within a memory. In other embodiments, a profile for an anticipated patient is stored within a medium associated with that anticipated patient. The medium may, for example, be a removable medium for external defibrillators.

Claims

1. A method comprising:

collecting information relating to a patient; and

storing the information as a profile for the patient that is retrieved by an external defibrillator for delivery of therapy according to the profile, in which the patient is an individual patient, the profile is customized for the individual patient and the customized profile for the individual patient is separate from a general profile for multiple patients.

2. The method of claim 1, in which collecting information relating to a patient comprises:

measuring a transthoracic impedance of a patient; and

determining defibrillation therapy parameters based on the measured transthoracic impedance,

in which storing the information as a profile comprises storing the defibrillation therapy parameters as part of the profile.

3. The method of claim 1, in which collecting information relating to a patient comprises recording a physiological parameter of a patient, and storing the information as a profile comprises storing the recorded physiological parameter as part of the profile.

4. The method of claim 3, in which recording a physiological parameter of a patient comprises recording an electrocardiography (ECG) signal.

5. The method of claim 4, in which recording an electrocardiography (ECG) signal comprises recording a first ECG signal, and further comprising, at least one of periodically or in response to an event, recording a second ECG signal, in which storing the information as a profile comprises storing the second ECG signal as part of the profile.

6. The method of claim 1, in which collecting information relating to a patient comprises collecting medical history information regarding the patient, and storing the information as a profile comprises storing the medical history information as part of the profile.

7. The method of claim 1, in which collecting information relating to a patient comprises collecting emergency contact information, and storing the information as a profile comprises storing the emergency contact information as part of the profile.

8. The method of claim 1, in which collecting information relating to a patient comprises collecting a do not resuscitate order for the patient, and storing the information as a profile comprises storing the do not resuscitate order as part of the profile.

9. The method of claim 1, in which storing the information as a profile comprises storing the information as a profile within a memory of the external defibrillator, and collecting information comprises:

coupling the external defibrillator to the patient; and

collecting at least some of the information for the profile via the external defibrillator.

10. The method of claim 1, in which collecting information comprises collecting at least some of the information via a programming device.

11. The method of claim 1, further comprising updating the profile at least one of periodically or in response to an event.

12. The method of claim 1, in which collecting information relating to a patient comprises collecting information identifying a medication of the patient, and storing the information as a profile comprises storing the information identifying the medication as part of the profile.

13. The method of claim 1, in which collecting information relating to a patient comprises collecting information identifying that the patient has an implantable cardiac device, and storing the information as a profile comprises storing the information identifying that the patient has the implantable cardiac device as part of the profile.

14. The method of claim 1, in which collecting information relating to a patient comprises collecting a biometric measurement from the patient, and storing the information as a profile comprises storing the biometric measurement as part of the profile.

15. The method of claim 1, in which collecting information relating to a patient comprises collecting information relating to a plurality of patients, and storing the information as a profile for the patient comprises storing the information as a plurality of profiles for the plurality of patients.

16. The method of claim 15, in which collecting information relating to the plurality of patients comprises:

measuring a transthoracic impedance of each patient of the plurality of patients; and

determining defibrillation therapy parameters for each patient based on the measured transthoracic impedance of each patient,

in which storing the information as a plurality of profiles comprises storing the defibrillation therapy parameters associated with each patient as part of a profile associated with each patient.

17. The method of claim 15, in which collecting information relating to the plurality of patients comprises recording a physiological parameter of each patient of the plurality of patients, and storing the information as a plurality of profiles profile comprises storing the recorded physiological parameter of each patient as part of a profile associated with each patient.

18. The method of claim 17, in which recording a physiological parameter of each patient of the plurality of patients comprises recording an electrocardiography (ECG) signal for each patient.

19. The method of claim 1, in which storing the information as a profile comprises storing the information on a removable medium configured to be received by the external defibrillator.

20. The method of claim 1, in which storing the information as a profile comprises storing the information on an radio frequency identification (RFID) device associated with the patient.
