Abstract

Various systems and methods are provided for intervening where aberrant heart and/or respiratory functionality is detected. For example, some embodiments of the present invention provide a monitor capable of detecting the occurrence of various aberrant events, and in some cases for intervening in the event. In some cases, a pacemaker or some other medical device detects an abnormality, and an information signal indicating the detected abnormality is transmitted from the pacemaker to a bedside monitor or some other monitor associated with the patient. Based on the received information signal, the bedside monitor can deliver an appropriate therapy. Such a therapy can be, but are not limited to, the sounding of an audible alarm to awake the patient, and/or the programming of a medical device implanted in the patient. Further, in some cases, the detected aberrant behavior and/or events surrounding the aberrant behavior can be transmitted from the bedside monitor to a remote monitor. Information can be retrieved from the remote monitor by a clinician and used in real time, or at a later time to diagnose and/or treat the patient.

Claims

1. A method for mitigating an apnea, the method comprising:

determining if a patient is in a resting state;

based at least in part on the resting state determination, generating an information signal indicating an occurrence of apnea;

receiving the information signal from a deployed, implantable medical device at a local monitor;

storing the information signal;

associating a time stamp with the information signal;

based at least in part on the information signal, autonomously selecting and initiating, by the local monitor, at least one appropriate therapy from among a plurality of available therapies for mitigating the occurrence of the apnea; and

communicating a message based at least in part on the information signal and the time stamp to a remote monitor disposed beyond the telemetry range of the deployed, implantable medical device.

2. The method of claim 1, wherein the information signal is received via a wireless link.

3. The method of claim 2, wherein the local monitor is disposed within an external telemetry range of the deployed, implantable medical device, and wherein the remote monitor is disposed beyond the external telemetry range of the deployed, implantable medical device.

4. The method of claim 1, wherein communicating a message to a remote monitor includes transmitting information over a medium selected from a group consisting of a cellular telephone link, the Internet, a virtual private network, and a public switched telephone network.

5. The method of claim 1, wherein the therapy includes sounding an audible alarm.

6. The method of claim 1 wherein initiating a therapy includes programming the deployed, implantable device.

7. A method for mitigating an apnea, the method comprising:

determining if a patient is in a resting state;

based at least in part on the resting state determination, generating an information signal;

receiving the information signal from a deployed, implantable medical device at a local monitor, the local monitor including diagnostics;

indicating by the diagnostics an occurrence of apnea based at least in part on the information signal;

storing the information signal;

associating a time stamp with the information signal;

based at least in part on the information signal, autonomously selecting and initiating, by the local monitor, at least one appropriate therapy from among a plurality of available therapies for mitigating the occurrence of the apnea; and

communicating a message based at least in part on the information signal and the time stamp to a remote monitor disposed beyond the telemetry range of the deployed, implantable medical device.

8. The method of claim 7, wherein the information signal is received via a wireless link.

9. The method of claim 8, wherein the local monitor is disposed within an external telemetry range of the deployed, implantable medical device, and wherein the remote monitor is disposed beyond the external telemetry range of the deployed, implantable medical device.

10. The method of claim 7, wherein communicating a message to a remote monitor includes transmitting information over a medium selected from a group consisting of a cellular telephone link, the Internet, a virtual private network, and a public switched telephone network.

11. The method of claim 7, wherein the therapy includes sounding an audible alarm.

12. The method of claim 7 wherein initiating a therapy includes programming the deployed, implantable device.
