Abstract
Embodiments of the present disclosure relate to multi-purpose sensors for monitoring a plurality of physiological parameters. According to certain embodiments, the multi-purpose sensors may include optical elements for determining oxygen saturation and regional saturation. In additional embodiments, such sensor may include multiple electrodes that are configured for bispectral index monitoring. In particular embodiments, portions of the multi-purpose sensors may be removed and discarded when no longer needed.

11. A monitor configured to be coupled to a combination sensor for pulse oximetry, regional saturation and bispectral index monitoring, the monitor configured to:
-
drive one or more emitters on the combination sensor configured for pulse oximetry or regional saturation; receive one or more photoplethysmography signals from one or more photodetectors on the combination sensor configured for pulse oximetry or regional saturation; receive one or more electroencephalography signals from a plurality of electrodes on the combination sensor configured for bispectral index monitoring; and determine if any of the one or more emitters, one or more photodetectors, or plurality of electrodes has been removed or disconnected from the sensor such that monitoring functions for one or more of pulse oximetry, regional saturation or bispectral index monitoring have been disabled. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
