Abstract

This document relates to receiving and processing signals during cardio-pulmonary resuscitation (CPR) treatment. This document further relates to establishing a localized, patient-specific network for communication of information from one or more sensors to a computing device.

Claims

1. A system comprising:

a sensor configured to be placed in contact with the skin of a patient;

an ECG lead configured to be placed in contact with the skin of the patient; and

a computing device connected to the ECG lead and configured to;

establish a localized, patient-specific wireless network;

perform an authentication process by sending multiple signals between the sensor and the computing device with at least one of the signals being transmitted between the sensor and the ECG lead using the patient'"'"'s body as the conductive medium; and

subsequent to the authentication process, enable the sensor to send and receive signals via the patient-specific wireless network.

2. A medical system for providing electromagnetic stimulation of a patient, comprising:

an electronic interface configured to receive data from one or more sensors;

an ECG lead configured to be placed in contact with the skin of the patient; and

a computing device connected to the ECG lead and configured to;

establish a localized, patient-specific wireless network;

perform an authentication process by sending one or more signals to the sensor and receiving one or more signals from the sensor, with at least one of the signals being transmitted between the sensor and the ECG lead using the patient'"'"'s body as the conductive medium; and

subsequent to the authentication process, enable the sensor to send and receive signals via the patient-specific wireless network.

3. The system of claim 2, wherein the computing device is further configured to initiate the authentication process based on a request to join the wireless network received from the sensor.

4. The system of claim 2, wherein the configurations to perform the authentication process comprise configurations to perform a handshaking routine during which at least one of the signals is transmitted using the patient'"'"'s body as the conductive medium.

5. The system of claim 2, wherein the wireless network comprises a body area network.

6. The system of claim 2, wherein the wireless network comprises a mesh network.

7. A sensor, comprising:

a wireless transceiver configured to communicate with a computing device via a localized, patient-specific wireless network;

a contact configured to be placed in contact with the skin of a patient; and

a module configured to;

perform an authentication process by sending one or more signals to a computing device and receiving one or more signals from the computing device, with at least one of the signals being transmitted between the contact of the sensor and an ECG lead connected to the computing device using the patient'"'"'s body as the conductive medium; and

subsequent to the authentication process, join the patient-specific wireless network.

8. The sensor of claim 7, wherein the sensor is further configured to initiate the authentication process by sending, to the computing device, a request to join the wireless network.

9. The sensor of claim 7, wherein the configurations to perform the authentication process comprise configurations to perform a handshaking routine during which at least one of the signals is transmitted using the patient'"'"'s body as the conductive medium.

10. The sensor of claim 7, wherein the wireless network comprises a body area network.

11. The sensor of claim 7, wherein the wireless network comprises a mesh network.

12. The sensor of claim 7, wherein the sensor is configured to monitor at least one of blood pressure, temperature, respiration rate, blood oxygen level, end tidal carbon dioxide level, pulmonary function, and blood glucose level.

13. A method for providing a patient-specific wireless network, the method comprising:

establishing, by a computing device associated with a medical system for providing electromagnetic stimulation of a patient, the patient-specific wireless network;

performing an authentication process that includes sending multiple signals between a sensor and the computing device with at least one of the signals being transmitted using the patient'"'"'s body as the conductive medium; and

subsequent to the authentication process, enabling the sensor to send and receive signals via the wireless network.

14. The method of claim 13, further comprising, prior to performing the authentication process receiving, at the computing device from the sensor, a request to join the wireless network.

15. The method of claim 13, wherein performing the authentication process comprises performing a handshaking routine during which at least one of the signals is transmitted using the patient'"'"'s body as the conductive medium.

16. The method of claim 13, wherein performing the authentication process comprises confirming physical contact between the sensor and the patient.

17. The method of claim 13, wherein sending the multiple signals with at least one of the signals being transmitted using the patient'"'"'s body as the conductive medium comprises sending at least one signal from the sensor, through the patient'"'"'s body, and to an ECG lead.

18. The method of claim 13, wherein the wireless network comprises a body area network.

19. The method of claim 13, wherein the wireless network comprises a mesh network.

20. The method of claim 13, wherein the wireless network comprises a localized, patient-specific network.

21. The method of claim 13, wherein the sensors comprise one or more sensors configured to monitor at least one of blood pressure, temperature, respiration rate, blood oxygen level, end tidal carbon dioxide level, pulmonary function, and blood glucose level.

22. The method of claim 13, further comprising:

securing one or more ECG leads to the body of the patient; and

securing the sensor to the body of the patient.

23. The method of claim 13, wherein the medical system for providing electromagnetic stimulation of a patient comprises a defibrillator.
