Abstract

An automatic rate response sensor mode switch is implemented in an implantable medical device to monitor and isolate any sensor in an integrated sensor scheme. The isolated sensor is based on identification of problems associated with the sensor. The implantable medical device will switch to operate with the remainder sensor(s). Specifically, an algorithm tests and determines sensor status to initiate and operate the sensor mode switch. The software continuously monitors, isolates or qualifies a sensor to come back on-line automatically.

Claims

1. An automatic rate response sensor mode switch implemented in an implantable medical device comprising:

a plurality of integrated sensors;

means for testing a status of said sensors; and

means for isolating a problem sensor among said plurality of integrated sensors to switch and operate with only the remainder sensors.

2. The switch of claim 1 wherein said switch remains fixed to operate with said remainder sensors until a reset is executed.

3. The switch of claim 1 wherein said means for isolating operates on a temporary basis and reconnects said problem sensor when a problem is resolved.
