1. A method, comprising:
- performing a real-time comparison of a first detected optical energy absorption profile of a first region within a biological subject to characteristic spectral signature information, the detected optical energy absorption profile including at least one of an emitted optical energy or a remitted optical energy;
determining whether an occlusion event has occurred;
obtaining a second detected optical energy absorption profile of a second region within a biological subject, the second region having a different location from the first region;
performing a real-time comparison of the second detected optical energy absorption profile to characteristic spectral signature information; and
determining whether an occlusion event has occurred.
