INDICATOR METRICS FOR INFECTION MONITORING
First Claim
1. A method for alerting that an infection is likely to be present in proximity to an implanted medical device, the method comprising:
- monitoring an indicator of infection in proximity to the implanted medical device;
determining whether a metric of the indicator crosses a first threshold indicative of infection for a first period of time;
determining whether the metric of the indicator crosses a second threshold indicative of infection for a second period of time, the second threshold being less indicative of an infection than the first threshold and the second period of time being greater than the first period of time; and
issuing an alert if(i) the metric of the indicator crosses the first threshold indicative of infection for the first period of time, or(ii) the metric of the indicator crosses the second threshold indicative of infection for the second period of time.

Abstract
A method for monitoring an infection in proximity to an implantable medical device includes monitoring an indicator of infection in proximity to an implanted medical device; determining whether the indicator crosses a first threshold indicative of infection for a first period of time; and issuing a first alert if the indicator crosses the first threshold for the first period of time. The method further includes determining whether the indicator crosses a second threshold indicative of infection for a second period of time. A value associated with the second threshold is less indicative of an infection than a comparable value associated with the first threshold. The second period of time is greater than the first period of time. The method further includes issuing a second alert if the indicator crosses the second threshold for the second period of time. The first and second alert may be the same or different.

19. A computer readable medium comprising instructions that when implemented cause an implantable medical device to:
-
monitor an indicator of infection in proximity to an implanted medical device; determine whether a metric of the indicator crosses a first threshold indicative of infection for a first period of time; determine whether the metric of the indicator crosses a second threshold indicative of infection for a second period of time, the second threshold being less indicative of an infection than the first threshold and the second period of time being greater than the first period of time; and issue an alert if (i) the metric of the indicator crosses the first threshold indicative of infection for the first period of time, or (ii) the metric of the indicator crosses the second threshold indicative of infection for the second period of time. - View Dependent Claims (20)

21. An implantable medical device comprising:
-
means for monitoring an indicator of infection in proximity to an implanted medical device; means for determining whether a metric of the indicator crosses a first threshold indicative of infection for a first period of time; means for determining whether the metric of the indicator crosses a second threshold indicative of infection for a second period of time, the second threshold being less indicative of an infection than the first threshold and the second period of time being greater than the first period of time; and means for issuing a first alert if (i) the metric of the indicator crosses the first threshold indicative of infection for the first period of time, or (ii) the metric of the indicator crosses the second threshold indicative of infection for the second period of time.
